Overall good game but some balancing issues.
When you hit ~23 you hit a wall since you have a quest to complete the next maze but its way too hard for that part of the game (monsters are stronger that what they should be and the boss...) and then the normal enemies around that level give too low xp so you cant level up basicly. Its not a paywall though. But still, i would give it a 4,5/5 if it would but it only lets pick 4 or 5. And idk if it has been fixed.
