I’m liking RpgO. The controls are good. You have a nice, one swipe to cardinal direction swipe. As a blind player and content creator, great controls are a must have. I like your tutorial pop-ups when starting your first battle. It is a well done tutorial. Your music player has no volume controls that voiceover can detect. I’d love to use your music. Also, the music has a significant skip, between loops. Monsters moving is great! Grid map controls are nice. Telling me which tiles are open, in cardinal directions is great! Objectives, on missions are very vague. Will i get the full game by purchasing the full game? Wil that give me all the music, levels, unlocks and the full game. I don’t want to buy the game and still have to invest in more unlocks. That is not explained in the game. Tiles that have not been explored should have a notation that that they are unexplored. That would be a great feature. Love the SFX that are in the game. More, please! More build up to boss battles or MSL quests, would be nice! I’ll play this game on my Youtube channel: Game Double Tap. It’s fun! Great potential! I look forward to future expansions. -- Game Double Tap, 2026-08-17 ### **--- "Too difficult" Died twice to the first monster. This games not for me. -- TK_200, 2026-06-23 ### ***** "I like the game." Good art, story, gameplay and art design. The music is so cute. This is good, please everyone, give it a try. The game is not free of course, is a premium game. Still is worth and very cheap. -- Delta_Red_Cammy, 2026-06-19 ### **--- "Can’t really play game" There are so many ads that I can’t really play the game. It was very hard to even find the way to pay to remove the forced ads, but then there are still a bunch of things you can only get by watching ads even after paying to remove forced ads. The one plus is that the forced ad removal is pretty reasonably priced, but I was already sick of the game by the time I found it. This could be a fun game but the horrible monetization makes it no fun to play -- Phoenyx23, 2026-06-17 ### **--- "Ad after every battle" Uninstalled -- KJHaley, 2026-06-16 ### ***** "Fun little old school-esque dungeon crawler." A fun little old school-esque dungeon crawler with a futuristic cyberpunk coat of paint and some rougelite elements. It’s like the old text based dungeon crawlers but from the far far future, if that makes sense. It’s great for quick bursts of action when you have a few moments of down time. I look forward to continuing my journey and unlocking more of the lore via the cute little built in terminal! Keep adding monsters and levels! Full disclosure, I received the ad free in app purchase for free. That being said, if your into this type of game, it’s worth spending money for the unlock. -- Electro Specter, 2026-06-14 ### ***** "Hackrun plus chips challenge" Fun little game. Like the selection of background music. -- theputer, 2026-05-19 [View all RPG Offline reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## RPG Offline Available In - [United States](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/united-states) - [Vietnam](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/vietnam) - [United Kingdom](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/united-kingdom) - [Canada](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/canada) - [Poland](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/poland) - [Singapore](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/singapore) - [Philippines](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/philippines) - [Sweden](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/sweden) - [France](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/france) - [Japan](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/japan) - [Brazil](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/brazil) - [Mexico](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/mexico) - [South Korea](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/south-korea) - [Saudi Arabia](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/saudi-arabia) - [Hungary](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/hungary) - [Netherlands](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/netherlands) - [Indonesia](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/indonesia) - [Azerbaijan](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/azerbaijan) - [Israel](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/israel) - [India](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/india) - [Russia](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/russia) - [Germany](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/germany) - [Italy](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/italy) - [Thailand](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/thailand) - [Türkiye](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/turkey) - [Senegal](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/senegal) - [Ukraine](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/ukraine) - [Uganda](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/uganda) - [Uruguay](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/uruguay) - [Uzbekistan](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/uzbekistan) - [Venezuela](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/venezuela) - [Norway](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/norway) - [Austria](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/austria) - [Bulgaria](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/bulgaria) - [Belarus](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/belarus) - [Czechia](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/czechia) - [Denmark](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/denmark) - [Algeria](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/algeria) - [Ecuador](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/ecuador) - [Egypt](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/egypt) - [Spain](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/spain) - [Finland](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/finland) - [Grenada](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/grenada) - [Ghana](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/ghana) - [Ireland](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/ireland) - [Iceland](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/iceland) - [Kuwait](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/kuwait) - [Kazakhstan](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/kazakhstan) - [Lebanon](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/lebanon) - [Sri Lanka](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/sri-lanka) - [Malaysia](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/malaysia) - [Argentina](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/argentina) - [Nepal](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/nepal) - [New Zealand](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/new-zealand) - [Portugal](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/portugal) - [Romania](https://apptail.io/app/rpg-offline-os-core-quest-gJHz/romania) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
