I like the aesthetics and background music, the game has potential but probably need to be fleshed out a bit its a bit bare bones(sorry for the pun). I Could dig build and "trick or treat" I could also get to the second level. I was just a bit unclear on the defense part. How do i get out of the hole do i need to build for that as well (i didn't seem to be able to) so after getting to the second level it was basically game over for me as the skeletons broke trough and got in the pit as i could not get to the top to attack them
But good job for what you managed to do
