The rule is simple but addictive and will get hard that requires strategy and planning to continue fight monsters. It is a combination of match 3 gameplay with a twist- broken up tiles of the same (spoiler) “Level” will form one tile of 1 higher level up. Example- break 3 Level 1 tiles will form a new Level 2 tile, rinse and repeat. Of course you can spend real money to empty the board and buy your way out of a jam but the grinding IS the game, IS the fun.
Charming retro midi track and pixel art. Reminds me of Family Com Nintendo games! Perfect play for waiting in line, sitting on the toilet (hell yeah), quick break.
Highly recommended.
