Thank you for your feedback and we're glad the game pleases you (even we don't know how we managed to do it in a week).
Regarding the keys, there was a strange mix between the WASD of a QWERTY keyboard and the A of an AZERTY keyboard. It's fixed now, everything is indicated for QWERTY. But I don't understand the story about the "x button that didn't do anything"... We have not assigned the X key to anything. Maybe you're talking about the X button on a Playstation-type controller ? If that so, it's for eating.
There was panels to explain the different states but we haven't had time to add them to the game. We'll try to add them to the description on the game page, ASAP.
