The game looked cool and played fine. I think there could be some potential to expand on this, but there needs to be a little more polish overall - obviously some things were hard to get to in a limited amount of time.
I think the sfx were too loud and the player dies too quickly - and I think reload time is too long for how big your magazine size it - it didn't really offer much off a strategy element since hitting the enemy didn't do too much damage. I was trying to hit them as much as I could before hitting the reload time making the battle more unfair than it needed to be. I'm not sure why there's a jump button since I never found a use case for it.
keep it up!
