Very fun but as others have said, this bitch lags down to single frames come third boss fight or so.
Sad, no 10,000 highscore place for me, even tho im pretty sure i could get it if i simply get 10 slime spikes, a few crowns and angel wings, and just stand still for a few hours as nothing can touch you and it becomes an idle game.
As far as actual negatives go, even for a demo the stages feel like they go on for just long to be annoying, i feel like u could shave 30% of a level and lose literally nothing
