I'll get on the bandwagon, give us the guuun!

Too bad you didn't have more time to finish it, I really dig the game mechanic.

I'm with @bloobyrd, I tried every single key on my keyboard to be sure that the gun didn't work :D

I'm just a bit disappointed we don't get to use that giant gun :D nice idea, good potential!

I know what it is to make a game in half a day, so even though there's no 'final goal', I think you managed to nail the theme with a simple, yet relevant mechanic. Well done !

For what you were able to make the game is fun.  There is a lot of potential here.
