Fixed a few bugs:
Ammo going into minus numbers,
some animation bugs on the enemies.
Added a few things:
Mechanics for the tutorial system are now in place.
I was planning on just making placeholder art for the explosions for now but this animation actually looks really nice. I'll probably tweak it at the end but I'm happy with it for the time being.
Also I thought I'd share some gun designs which I'm adding slowly.
