Nice game! I especially liked the scorpions! Did you design them yourself including animations? If so, impressive work!
Some points for potential future improvements:
- Gun could use some more "juice", meaning muzzleflash, recoil or even full-auto. I tried different guns but they didn't really feel that much different except for the damage?
- Maybe add some hitbox for "headshots" so it becomes more skill based. Right now, every fight is start-shooting-and-walk-backwards because they take 3+ hits.
- Enemies don't block you. Once the timer ran low, I just ran through them taking little damage while searching for the exit.
- Some kind of progression. With these kind of squared levels, it would be easy to create some tiling that is randomized. That way you could make the levels longer/more difficult if the player advances.
Keep up the good work!
