This game is truly giving you the pure roguelike experience a mobile game could offer, pure fun and mechanics, no premium resources (for now).
You were given 4 heroes to choose from and their gameplay really differs so much.
The controls and the characters are easy to understand and learn but it would be quite hard to enjoy in depth, because you might hit frustration at a certain boss.
Go try it! I am really happy when i found this instead of playing the other "roguelike" games that were offered in the current
