Nice work it was a whole product. I did find the game very frustrating to play though! I would always hit the wrong button and ended up getting stuck. It was hard to make progress cause it felt like I was fighting the controls instead of the game.
I also found your secret, but didn't even know it was a secret! Unfortunately clicking does freeze me out of moving my character so I could not progress from there.
Also, I could not figure out how to beat level 7.
Well done thought!
Keep making games!
EDIT: Liked the music a lot :)
