Hello friend, I tried your game, this chevre and I found 2 bugs and only reached level 2. I speak Spanish (I am using the translator) and if I would be interested in helping you create a few levels as long as time permits.
If when jumping and the character is very close to the edge, the fall animation is still there. and the other skeleton shot a Martian while I was moving and I hit him next to him and I touched him and the enemy flew out and pierced everything
