Congratulations on making something for the jam, it's a good first step.
I guess I'd like to see some more heart. Give me a sword that looks distinct. It sounded like a laser gun, maybe it could have been a laser sword? Maybe there could have been a counter on the door to show that it's tied to how many enemies are left?
There's a lot of directions you could take it. I look forward to seeing what you come up with.
Thanks for sharing and good luck in your future projects!
