This game is still fun! I keep coming back to play this game over and over, and that's because the core of the game is simple for a collect-a-thon with stats, and it's been executed fantastically!
I love how, despite losing practically every important stat when you fail the nightmare sequence, you still learn everything FASTER! Sadly, this game has also shown to be extremely buggy. Losing momentum when I land, having the shadow somehow disappear(It can still hurt me, but it's invisible and not doing anything), the fact that you can win the shadow fight by basically standing still if your defensive stats are high enough, your acceleration(and by extension, deceleration) being awfully slow and the graphics, even though it's very simple, being rather flat for certain tiles.
Overall, very good game. It's simple and fun to get 100%, and it's not very tedious at all, and there's even some replay value in the medals, but the insane amounts of bugs, whether it be game-breaking ones or just annoyances, make it hard to rate any higher.
Still waiting for news on the sequel... or is it a remake now? Hard to find news of what you're doing...
