Dash (j) does not work, and there seems to be no way to close the app other then the Alt F4. But it looks nice.
If its locked you should somehow communicate it to player :), otherwise it looks like something is wrong. Also you should have main menu under Esc it's a expected behavior. I've played it about 10 minutes and uninstalled. Wish you good luck with it, but don't plan to play it further. If i had time i still have Ori and three parts of Trine to finish :)
