This was really fun! If this were fleshed out a bit, with more levels and a few more buttons/mechanics, I could see it being a full game!
My one super minor recommendation would be to have the w/a/s/d keys laid out in the "inverted T" pattern (like they are on the keyboard). It would be a little easier to see at a glance which directions you had enabled. Other than that, I think you've got a really nice prototype here.
I liked the "Im out of brain cells" message at the end. I think we all feel that towards the end of a game jam lol
