Really fun! Jump is a little floaty but the graphics are nice, the music is spooky for the season; and everything comes together nicely.
I'm pretty sure I also got a few enemies to kill each other which was pretty sweet; then I figured out I can attack them. But enemy on enemy violence and trying to push them off the map was a lot of fun.
Also if you jump against a wall you can catapult yourself, I did this a little far and fell into a wall.
The damage feedback mentioned in other comment(s) would definitely help a bit.
