Nice! Quite good for a first jam, The intuitive UI especially, telling the user which keys to press and having a timer on screen. I made it all the way through.
Also little advice is I'm not sure if the ability to escape the stage was on purpose or I missed a secret there, but it made an other wise pretty complete game, feel a little less complete. Also the enemies, if you do an occasional raycast for line of sight, makes them feel a lot more fair and real.
Great job!
