0.0.1 update

Hello players!

After a 2 month break i finally updated MathCore! Nothing crazy but I optimized a little bit the Expressions in the projectiles so it runs better on small devices even if you shouldn't play this game on your phone...

I also fixed the bug where you could not select a skin from your files so go crazy and import whatever you want to fight mathermaticians!

I think I'll do improvement to mobile controls and add a new boss for the next version.

Hope you have fun playing MathCore!
