Nice Game, its more fun killing your enemies than in my game XD i made something like this too where you can only shoot once with a weapon but i spent more time adding mechanics that i couldn't add more weapons.
I understand. I also wanted to add so many other ideas like traps and little interactions around. or at least classic exploding barrels. XD and my game has elemental damage and each enemy die with only one elemental shot. it was my first jam so I didn't know about spending more time on polishing than adding stuff.
well have a good day. ^^
