I liked the style of the intro and generally the spritework! Nice concept, picking up your own slime felt oddly satisfying!
I had a bit of trouble with the big collision on the player character both with movement and avoiding projectiles. I also initially got confused by the arrow, thinking it was telling me to go to a specific direction, before I figured out it's basically my crosshair... but I think that might just be because I'm tired from working on my own entry :D
