Nice work - I found the game to be enjoyable. The visuals look great, but don't have nearly enough contrast, which made it hard to see what was going on with the game.

I like:

• the rain effect! It suttle, but does the job!
• the "opening a can" sound effect! Without it does a lot to sell 'em as being actuall things.

Optional suggestion:

• I had a hard time making out what was goin on, as everything has a very similar value. Maybe add some contrast to the player and buildings, soo they pop a bit more?:)
