This was fun and the name is great too! Wish it was a bit longer but it was a bit of a challenge to get around all the nails. I think the jump was a bit high and would have been good to put in some platforms at various heights.
The head on the character looks like it has its normals flipped. You can go into Blender and display those or recalculate them to the outside to fix that. You can also customize the menu buttons. I love the fact you used a UI overlay for the E key to pick up.
Great job on this! I think you have everything covered.
