I got this game for free out of a magazine, i have to say, i would not pay for this game.
Don't get me wrong, its not bad, but it's just not good enough to warrant a buy.
Controls: Kind of wonky, they feel slippery and its hard to calculate jumps
Music: Atmospheric, pretty.
Visuals: The best part of the game, it has its own style, and looks quite nice
What really kills the game are the controls, it just doesn't feel worth a time-spend.
Definately not bad, but not good either 6.5/10
EDIT: After giving this game a second chance, i played for another half hour.
The platforming is extremely easy, but wonky, so falling always feel like the game's fault (i've played VVVVVV, IWKTG, and tons of other hard platformers, but this is the first one that feels like a cheat.)
I got to a boss, don't know if its the first, second or third, but the game suddenly became impossible, millions of projectiles, combined with the slippery nature and the fact that you die in 1 hit just feels idiotic.
Go buy pokemon emerald, this is not worth
