Looks very cool. Played for 1-2 minutes and enjoyed it. However, the keyboard commands (space, ?, M, V, E, etc.) don't seem to work with Chrome. I had to use mouse to trigger commands, but then it asked me to enter ESC/SPACE to continue but these keypresses do nothing.
Due to how the canvas captures the mouse for other purposes, one needs to click on the light background, not on the canvas directly, to give focus to the frame, so that’s why I put those instructions. I normally use firefox, and that works without issues there. If I understand, those instructions didn’t work in chrome?
