This was quite a lot of fun :)
Loved the artstyle, and the gameplay.
I had some problems with the controls. Using a controller didn't work for aiming.
Also when aiming with the mouse, it never seemed to aim at where I was pointing. It was always about 10 degrees off.
Here are some ideas to flesh this more out:
- Give the player at least a highscore to motivate him to keep on playing. (e.g. Zombiecount + Time survived?)
- If you want to make this competitive maybe add an online scoreboard to it as well.
- Maybe add some zombie variants to this so it doesn't get stale after playing for 10 minutes.
