Simple yet frustrating:
- The "puzzles" make up the rules as you go
- A lot of timing-based puzzles
- A lot of backtracking
- One-hit-failure Bosses

The positives, style and overall originality of the mechanics, do not outweigh the negatives.

I loved it, genius puzzle design and great artwork... although the cozy game in the beginning gets quite challenging at the end.

What a wonderful game.

Seriously, what a wonderful game.

This is a puzzle game that really captivates you from the get-go. It starts out simple, and gets more complicated until the end, but at no time do you feel overwhelmed by the task at hand. Each concept is clearly shown to you and you are given enough time to master it before moving on to the next, until finally you're handling all the teachings of the game at once, flying through at a rhythm that just feels right.

I have not played a game this creative since I played the original Portal back in 2007. The ideas here are basic, just like walking through portals can be, but with everything on your plate the execution gets complex and beautiful. Everything starts feeling second nature, and at times when you want to try something out to see if it'll work, you'll find yourself amazed that it does.

I very highly recommend this game. While it didn't come out this year, I played it this year, and it's definitely on my best of short list now, along with Dave the Diver (also played this year) and Tactical Breach Wizards. This game isn't similar to either of those, but in terms of enjoyment had this year, those three are at the top.
