It was really cool that you made everything from scratch! I'm a really big fan of the simplified cube aesthetic! I'm glad to see that you'll be continuing work on it after the jam, because I think the gun switching mechanic was a good concept! Really liked the music and sound effects! They fit the world perfectly! I think the other comments have summed up what could be improved on for the future update, so I won't go into that in my comment! Great work!
