Uhm... Well the enemies were already in a loop... And didnt seem to die... nor could they attack me.
I couldn't see any pickaxe...
And the display was squashed along the x-axis.
My suggestions would be to fix the enemies, give the player a health bar, and the enemies a health bar, and a big one for gamejams, try make the game mechanics first. The core game mechanics come before you design the levels. :)
I hop you can make more fruitful games for future jams!
