The visual took time to get accustomed too but it's not that big deal. However, when stuffs overlap, it's hard to know what's going on for e.g there's a room with lots of slime, golds, furniture, projectile shooting monster and spikes. Spike couldn't be noticed unless i take a close look at the hp bar. Receiving damage "juice" should be improved too. The light doesn't turn as fast in the corner so if there's enemy waiting it would be disastrous.
It's pretty fun if you know what's going on.
Personal preference: i feel slime shouldn't bleed. Shouldn't they explode in gooey form?
