We intended to do key binding in the menu and the player should be able to restart the scene with the R key (like during the level), but we ran into some last minute issues and ran out of time before we could fix that.
I also keep getting the HJK wrong, but I thought I was just being bad, I didn't make the correlation you made. Hahaha!
And thank you for playing and for the feedback! I'm glad that you like it! :)
