Fun little game :D
I saw someone mention Death Road to Canada and I have to very much agree, hehe ^^
Game has a fun gameplay loop, smaking some people. But I saw that you also struggle with performance when there's alot of enemies on screen and go behind a wall...
We had the exact same issue, aswell as the walking into each other, heheh :D
But since I wont take this into aspect, I can say: Well done, my friend ^^
