Fun! little puzzler really had me thinking & performing mental maths under pressure! nice job! would have loved some music though!
i found myself getting very frustrated & wishing i could draw L shape lines & had a little Eureka moment where i realised i COULD draw L shaped lines as long as the "cut out corner" of the square was a tile id already gotten & that made me start playing a lot better!
I thought i had beaten your highscore but apparently I had just broken the timer somehow and been accidentally playing on infinite mode aha
