A nice simple take on the theme that provides a lot of opportunity for exciting and varied gameplay :) I like the aestehtic of the game, even more so considering you created it all yourself! As many others have mentioned, the cooldowns for the switch is kinda long but this is something that can easily be tweked post jam and didnt take away too much in my experience.
You should deifnitely consider expanding on this after the jam! Nice job :)
