Nice game with rooms for improvments.
I like the idea for multiplayer at same comp and idea about multiplayer over web(there aren't games like this for online mutiplayer).
few suggestions
- bigger screen
- Make so u can get out of stalls little easier
- health bar(no single shot kills plz)
- make bullets do rendome damage
- landing back in garage give u ur health back
- control speed
Nice game keep it up :)
