An evil game that made me smile XD The tone here is great, already a lot of flavour to the different enemy types and aesthetics. It was immediately into the loop and second nature to control and understand.
The set up of some enemies having special abilities or possession requirements fits into that 'Suika Game' design of readable hierarchies, and that's a system that could be expanded as far as you'd want which is so flexible. With scenery/building obstacles or different styles of top down movement (depending on who you possess) this could really be fleshed out into a full game, congrats!
