I've been told that there's an issue with small screen sizes. If the tutorial box that pops up at the start is blocking your view, you can resize it by grabbing the edges and move it by grabbing just above the top. Then once you are done with the instructions, you can close it by pressing the cross.
Since this isn't a game breaking bug, we won't be fixing this until the end of the game jam rating period. Apologies for the inconvenience!
