I like your game. It's a nice take on the limitation. Also it's a polished and jucy experience for a game made in 3 days. Those coloful explosions were satisfying. Nice work.
A minor imrpov I think, would be to enable the 1st weapon by default without clicking. But it doesn't take away from the fun!!
Would love if you'd take a look at my game:
