Fig. 8 Brilliant concept...
The idea behind this game, along with the artwork, is really beautiful and original. The whimsical music matches perfectly with the game's layout and the monochrome colour scheme with that colourful trail is really pleasing on the eye. However, may I suggest adding something to be able to slow the screen's movement down as well as being able to slow the bike? Although the game was initially very enjoyable as it got steadily harder, it got more and more frustrating because either the bike couldn't keep up with the screen or the screen couldn't keep up with the bike. This made it harder to navigate tricky bits and also harder to get checkpoints.
Other than those minor points I think it's a really addictive, beautifully portrayed game that I loved playing. :)
