What a really fun game! I love the models and that projectile physics on the blaster, magnificent. I did notice that you seemed to have jumping stackable. This may be intentional, but I remember when I tried to implement double jumping for the longest time, my double jump wouldn't feel like a lot of other double jumps like, it'll feel weak when I try to jump while going down. I later learned that a more "natural" feeling is when you reset the y velocity to 0 every time you jump (right before you add the force). Sure it's not realistic but double jumping isn't realistic anyways. Either way, great job with this submission!
