A good challenging game.
I remember playing Wario Ware and Mario Party games that were similar to this, but this one had much more variety. The animation and controls were very smooth, that made it much more fun to play. You get an exciting vibe when playing it, mainly because of the upbeat music and fun images you can trace. The spiral level on easy mode was probably the most difficult picture I had. I entertained from beginning to end.
The only thing I didn't like was that some of the levels were fairly repetitive. Just making the lines change the direction that they point in really didn't add that much of a challenge. Aside from that, I thought the game was consistantly entertaining and thoroughly enjoyable. Keep working on these party games, they are a blast to play. Keep up the great work!
