Tank themed demo. The tank looks nice and there is at least a green background. You should list the controls in your Author's Comments. I managed to drive the tank, but every obstacle killed me. You should add a health bar, because tanks should not die in one hit.

I don't understand what I'm supposed to do. Could you provide some instructions. Your tanks, crate, and canister sprites look cool though, so I will give you some points for that.
