I like the mechanics, but I kept encountering a bug where he would be stuck midair =/
Good level design!
Yes unfortunately this is the main bug which happens if too many buttons are pressed simultaneously. We've actually fixed the bug, but I believe we are unable to update the itch.io page until after the jam voting has ended. For now you can get around the issue by restarting the level ([esc] to pause and hit restart or alternatively hold [backspace])
