I liked this game! The concept of constantly changing weapons and having to plan on the fly is always fun for me. The sounds are beautiful too. And the color-coding was really helpful as well.
If I were to make a suggestion, it would be to have some sort of win state, or at least a points system. I definitely lasted longer and defeated more enemies upon multiple attempts, but there was no indication of that. (Unless there is a win state, and I just never got that far haha)
Fun game, keep up the good work! =)
