heres a small game I made inspired by three points:
touch to rotate the square and make sure the colored balls hit the matching colored sides.

-- Same as a % b, except that if a is a multiple b it returns b not 0
function specialModulo(a, b)
local mod = b * (a/b - math.floor(a/b))

end

EDIT: Fixed a bug with it turning wrong after a restart, added a max speed for the balls
