Hi! Thank you so much both for trying the game and taking the time to post this. That bug have been annoying me for a while, and it appeared after a tried to optimize the game a bit more, so I didn't redrew and erased more on the screen than absolutely necessary. I was just so close to finishing the game, and just didn't have more energy to fix that bug in the final hour. I will probably look at it once I recharge a bit of energy :) thanks!
