I suppose the concept is pretty original, yes, but I think that's for a reason... there's just no way it could've worked. A puzzle platformer where the puzzles are easy and the platforming is clunky. Spend several minutes on tedious puzzles only to fail a jump and have to restart the entire level. Whoops, that looked solid, but apparently it isn't. Item babysitting is really fun, especially when the entire game is focused around it.
Sigh. I can't be nice to this game, there's not much enjoyable about it.
The "puzzles" in this game are not ever too challenging. The hardest part is figuring out whether or not what you're trying to do is actually possible, since it's often ambiguous. Move speed is slow, jump is barely passable in height. It's not really a very good platforming engine, and the physics are often clunky. There's some decent brainteasers in the game though so I'm not going to pretend it's devoid of real puzzle design, but the tricky stuff is tricky for the wrong reasons. A lot of the puzzles seem to want to make you explore the area a bit and then restart because you did something wrong while exploring. And there's not a lot of variety; lots of the same things over and over with no clever twists on them.
The game's also way too punishing for how long some of the puzzles go on. Way too easy to jump up onto a box but WHOOPS you forgot to leave your orb next to the box so it plummets into the abyss. Fail a jump you're not sure you can make and WHOOPS back to the start. Losing keys also happens frequently. And the physics lead to some fun times, enjoy your accidentally crushed orb please and thank you. This is especially annoying in the levels that are comprised of several smaller puzzles instead of one big one. Screw up one puzzle and you have to redo all the others too, even though there's no good reason to. The puzzles are already tedious enough without the game forcing you to play them over and over again to figure out everything about them.
In short, it's not fun. At all.
The art style is okay, though the lack of color results in everything looking pretty samey after a while. The music's way too overblown for the game and there's far too few different music tracks. The game has too many levels, could've stood to have less considering the lack of variety, it just feels overlong. Especially when there are levels without any puzzle to be found; not kidding. I think this would've been better with a Braid-like rewind system to avoid the tedium of having to replay everything whenever you screw up a puzzle, honestly. Even if it's a "ripoff" that way, well, at least it'd be more fun to play.
Not recommended at all for either puzzle fans or platforming fans, there's far better out there than this.
