The puzzles are great and dimensions are neat, but platforming sections are particularly disastrous.

This game has many pros but one really annoying con. First with the pros: the dimensions are an innovative way of puzzles, it definitely borrows a lot from portal both in the humor (a lot less clever humor, however, but always charming as are the graphics) and the puzzles (nothing too complicated, nothing too easy). The narrator is always keeping you entertained (although when you die and hear the same thing over and over it becomes annoying as hell) and the corridors between levels are repetitive but never too long. There are some collectibles and times to beat or amount of switches between dimensions per level, but replay isn't a selling point.
The real con here is platforming sections: the first person view along with a really disastrous jumping make some relatively simple sections become as hard as Contra (okay, maybe exagerating, but many levels will have you replaying over and over because of one jump.
Checkpoints make this problem a little less important, but it will test your patience. Story could've not been there and the puzzles would've been the same, but the constant narrator and Ike and Dolly make for some smiles that diferentiate this game from others.
It definitely won't win awards and they definitely shouldn't make a sequel. It is nonetheless a charming and entertaining game for as long (or short) as it lasts.
