music and sound effects are bopping, the art and visual was also awesome, the feed back on enemies killed and shooting was also good, although I always seem to forgot I got allies XD, so why not make an ally that can deal damage only to a specific enemy or add in a sniper that always hits a perfect shot so It makes the player use the cover guy, also the player shooting perfect shots was nice and all but could you add a bit spread to the gun shooting so there's a bit of randomness
amazing game good job :D
