Solid entry, is a little rough around the edges though could use a bit of polish. Shooting is great and the controls feel responsive.
I was getting caught on the corners of cliffs, the hitboxes to stop you from walking near are very large near some of the corners. Also you can clip your head underneath the cliff from the bottom, gotta check that ysort. And obviously, it would benefit from a few sounds. The camera was very close, and I feel like you would have benefited from zooming it out a good bit.
Good entry, I think you could continue working on this after the jam and really work on polishing a lot of the gameplay elements. Good work!
