Peak Art Style. This game is more of a sequel than a remake of Bit Generations: Dotstream, as it expands pretty much every mechanic introduced in the original while adding new ones, mainly the 3D aspect, which adds more depth (no pun intended) and strategy to the gameplay. The final courses (and especially the final tour mode) are very challenging, but the game never becomes too frustrating. Also the presentation is great: visually I think its style will never age, and the soundtrack made by Hiromichi Fujiwara is top notch, easily one of the most peculiar in any Nintendo title.

Like the original game, I think Digidrive's learning curve may seem a bit steep in the beginning, but once you familiarize with all the mechanics the game becomes really addicting and I found mastering it very satisfying. Definitely one of the most complex and original Bit Generations/Art Style titles.
Overall I think I liked this DSiWare version more than the GBA original, because the dual screen makes everything more readable and thanks to the medal system you can always keep track of how many unlockables you got and in which mode.
