Took me a while to understand that you could click to possess enemies, you should certainly put some sort of control instructions on the jam page if you don't do so in game. The concept of this control enemies to stealth through areas could work really well if implemented a bit better, as restarting the moment the player gets caught is jarring, doesn't communicate the error, and it makes for really unforgiving gameplay. Having the mages shoot bullets until they loose sight of you could be one way to mitigate this, as well as making some sort of indicator of how long you can possess an enemy for.
