5 stars: Great way to pass time. So far the levels are not too difficult. Which can be a good thing if you want to relieve stress. Would be nice if levels could be organized into difficulty settings and/or add different play modes, i.e. time attack or multi-player mode for competition against other players or find a way to introduce other challenges within the game. Overall review is well done. Keep it up!
4 stars: The puzzles could be a bit more challenging, it's rare that you find one that isn't just a straight line to finish. I've also noticed a bug where I come back to the game later and have to replay the previous puzzle/level. Not a big deal if I'm doing a bunch in a row but annoying if I'm only doing one or two at a time. Fun game otherwise. Almost like a digital fidget cube.
3 stars: 90% of the levels require no thinking whatsoever. They look complicated, but there's only one path to take. Eventually the levels get reused, but the block is turned so it looks slightly different. Good concept, but the levels need more thought put into the design.
3 stars: No issues with playing game or glitches. Los of ads, (to be expected). I'm on the 400's and the frequency of trickier puzzles has improved. Otherwise, it's not hard to paint when you only have two choices on direction. I definitely like when there are more choices of direction. Occasionally, you can paint yourself into loop that you cannot get out of to completed.
2 stars: It was a vaguely entertaining ...
