Brilliant.
I loved this game, mainly for three key reasons;
1. The gameplay; not too hard, not too easy. Almost perfect. Plenty of checkpoints around as well so you don't get flustered. It is also a good concept to be driving a bicycle around huge shapes, slightly weird but wonderful.
2. The art; It was wonderful to see how arty this game was, from start to finish. I liked the idea how you create lines of purple paint behind you as you cycle.
3. The music; This flowed very well with the gameplay. It was very chilled and relaxing. It really got me into the mood of concentration, and helped me like the game more.
Overall, a fantastic game. Hope to see more of your wacky and beautiful ideas!
