Addictive Frustrating but in a fun way. Highly addictive. Excellent time waster tool.
Superb! So frustrating at times, but then the reward of a "YES!" moment when you clear a tricky level. Hugely addictive, you'll be telling yourself "just one more level" for a long time...
Madjoao Awesome addictive game!
Top notch! Good fun, and challenging enough to make it last without it becoming annoying. Had a slight issue with the background image not filling the screen but was easily resolved by changing settings from "stretch to fit" to "zoom to fit" Thoroughly enjoyable!
Great Game! The graphics could be better, but this neat little puzzle game is fun and frighteningly addictive, and that's what actually counts, right?
Easy to learn, difficult to master Great little game, like drawing in light with your finger. Gets puzzling toward the later levels and has excellent extra levels.
Fix for Nexus 4 handsets.
