Thanks for the feedback! It was quite late when submitting so I wasn't thinking when setting up the itch.io page :D. Yeah, sadly we(mostly I) ran out of time to properly explain how the game should be played in the tutorial :S and compromised with an explanation on the itch.io page.
Regarding the UI, I honestly don't know how I always find a way to screw it up for non-16:9 resolutions. I should probably polish up and put more effort into it as this has been a repeating thing for me.
