Hellooo, i found a small bug, i can´t move on of the clockparts to the right. i tried it on an gba and on an gbc. itßs on the first "puzzle" the part on the left side. i can move it up and down and to the left, but not to the right side. so i can´t finish the first puzzle on an actual GB :D
beside of that, the game locks awesome for that short of time :)
