I feel obligated to put any comment here, because you took similar approach to mine in this jam ;)
Ok. I think I know what happened.
love.js hides the mouse cursor, but it doesn't capture keyboard input until you click at the game window, even if you switch to fullscreen.
Can you give me your browser's console log?
I thought it's only required for game to use two colors.
Definitely one of most complex submissions for this jam. Unfortunately transfer through the scenes is buggy.
I kept the game open in another browser window for 5 minutes and I still have 5 lives. Box destruction visual effect is quite good. Used font is inadequate in my opinion.
i just did. Thanks
