The concept is nice but there are some things that require a little more work in my opinion:
- The enemies tend to spawn behind the player - it seems unfair
- You can get stuck by running our of ammo (and you can get -1 ammo as well)
- The red flashes are a little too slow and too in-the-face - a hurt sound would have been better in my opinion
- The art styles don't match - the grass doesn't fit
- The crosshair is a little too big
Overall I still enjoyed it, but it needs some improvements.
