nice graphics. I really like the art. the delay in shooting really makes it challenging to time your shots.

Pretty cool looks kinda like my game. Bobby Bow

The art of the cop flying backwards is hysterical!
I really like the slow reload mechanic. Gives it some nice press your luck strategy.

Also funny how many times I misread Skewer Combo as Super Combo. I LOLed when I finally got the joke.

It's a classic design (not the shooting cops bit!), but the implementation brings it down.

The crossbow is extremely fast and as a result avoiding damage is trivial. The enemy waves don't really become any more difficult as you play and in the end they completely stop. Even the road ends after a while.

You should create an enemy wave generator script which keeps increasing the difficulty slightly every wave. At some point the player is going to take a hit and lose gaining a highscore.

Also the .pdb files in the build are completely unnecessary, they only increase the build size.
