Alright, I played the first 5 levels of this game (AND I BEAT THEM ALL WITH A MOUSEPAD).
I might return for the rest later.
It's definitely not a bad game.
The graphics are of course not the best, but they are quite cute, so you can definitely enjoy the game nonetheless. (Got to love how those bird-enemies look. Btw, the enemies were the most dangerous creatures in this universe; I died like a million times.... Don't play this with a mousepad...).
The music however, is the best. Step is the very reason I came here in the first place :p
Gameplaywise, I'd say this is a pretty difficult game; it takes practise to 'master' the ball's movement. Mainly, this game was very smooth. However, at some parts things became a bit nitpicky, imo.
Even the puzzles were challenging at some points, which is a good thing. I also liked the way you introduce a new item, and thus a new game element in every new level.
This was without a question a pretty original game, so I liked that as well. Of course, since it's a ball/platform game, it bears some resemblance to the pretty old game wOne, if you've heard of it (especially in level 3). Then there's level four, where "Automation" is featured. I think that its structure actually is pretty similar to that of "Slippery Climb" from the Crash Bandicoot game :p
I could go on for ever in this review if I wanted to be picky, but there's no need for that.
Overall this was a good game, and good job winning that award ;)
