There are a few problems to this game
The enemy tracking as previosly said is problematic since the enemies move way too fast and either u or the enemy become a trampoline for the other (Which is great to see btw)
Also there seems to be no set direction to this game, and at one point I got caught in a limitless fall.
On the other hand the shovel animation and the fact that there are accessible chests is a nice feature. Which is the same with the health bars.
As a whole, even with it's problems, this is definitely a good bit of fun to play, good job :)
