The interpretation of the theme is like nothing else I've seen. You have to LOCK IN two buttons out of those available. I wish I'd thought of that.
I think I figured out what I was doing, it made more sense when I saw your not about the bosses, but some more explanation of the mechanics would be helpful.
I hope you'll develop this beyond the jam because it's such a unique concept. Breaking through the time limit you could really have something on the other side. Nice one!
