Yeah that exit button is quite redundant i realized that later but left it there. I am too used to making desktop games 😄. That brightness problem didn't even occured to me. Well lesson learned for next time. Anyways thanks for playing!
Its really really addictive, I just spent nearly an hour trying to get on the leaderboard (no luck sadly :D). My only complain would be the removing of the pieces, lost a few minutes on figuring out how to do that. Map it on the left mouse button maybe ?
