It’s ok not bad not great, I find that z is a terrible placement for the shoot button ether change that or make it so the up arrow can jump. Also it’s pretty easy, I think the bullets should go faster, and it should break when it hits a enemy. if you fix those problems I think it would be a full 3 out of five but right now 2.5 out of five.
Even though I worked on it I was kind of just watching him make it. I only started make some sprites a bit later
