Oh man, this one was great! I'd argue it's possibly the hardest in the series (yet)! In fact, the first time I tried beating it, I got stuck on one of the last puzzles, and it wasn't until now I actually figured out how to solve them!
Am I the only one who thinks that the defualt movement speed should be the final movement speed upgrade?
Seriously, you move WAY too fast to dodge accurately at max speed
In fact, even the default speed's a bit hard to dodge with!
If I could add any stat I wanted into the game, I would definitely add a secondary crystal boost that increases how many crystal you get at the end of a race. It'd have to be costly, though. Probably double XP needed for it. Thumbs up if you agree. (Which you probably don't, but whatever.)
Dear Arkeus:
Why the f*ck did you think it was a good idea to give every boss invincible projectile-shooting enemies AND infinitely-spawning (but killable) enemies?
I mean, that's a little much, don't you think?!
