bad design
EVERY THING IN THIS GAME IS AN ADS!!! like 80% of everything you see in this game is an ads. You see a box -> ads, you see a door -> ads, you enter the boss fight -> ads. The game play is kinda good tho, but the pop-up ads of everything is making this game suck. For exp, when you enter the boss fight, an ads pop-up right after you enter the area, and you have to turn it off when the boss still hitting you.
