Circuit

This game seems to be amazing, but there are a few points you should consider in polishing it ahead of time -

• The controls of the game currently don't feel right.
• There is no Aim Point for the Guns making confusion on the direction of the shoot. 
• The graphics of the overall game can be a bit better soothing to the eyes. For some reason, it's a bit distracting.
• The sound used in this game is not that suited to the game theme.
• The Bullet Should be fast enough and not this slow. 
• And a few more which you can check and tweak yourself.

But once you tend to fix and polish this game, this could be a great game to play.
