It’s a pretty good game, the adds are optional which not many of these games have. There are skills, offline gainings for coins, upgradable monsters, gacha, more difficulty’s different maps.
but sadly no fast forward, or a way to increase the speed of game so you don’t have to wait that much which. in my opinion is recommended since every enemy is about the same speed and every round is about the same length which gets quite long, so i’d rather have faster enemy’s the further you get.
But over all it’s a really fun game!
