It's really fun for lots of hours, but once you reach a certain level I feel like once you start another game it's hard to get motivated enough to start this one again. Also there are lots of alternatives now.
Same like Vampire Survivors I was obsessed with this game for a few days, then something else came along and I abandoned it. Still: great game that you could always play for another 30 minutes.
I loved everything about this game except for the boss battle, it frustrated me to no end. So I cheated on the last boss to finish the game and I feel no shame.
