I really wanted to see the ending, but I just can't do it. I got to field #9 and had some glitch that was allowing me to get one of the crystals, so I kept waiting for the crystal to respawn and lit up all that I could... Then the only thing that was stopping me was that blue square. Thinking it might be a bug I reset the stage, but all that did was take away my progress and the bug that allowed me access to the one crystal. I really couldn't figure out how to get passed it and just didn't have the patience. I enjoyed the gameplay, but the need for crystals was annoying... and #9 confused me.

I'm trying to find a walkthrough so that I can see the ending, especially since everyone says it's very good. Sadly I'm not having any luck and may never know. :(

Wow! I just spent 2 hours playing this and I was amazed. The puzzles were really fun and hard enough to be challenging, but not hard enough to be completely off putting. I really enjoyed the story and the control scheme was odd, but easy when I got used to it. I know this game is a bit old, but I really want to tell you that it was great.

I don't understand, nothing is working. clicked everything on the screen, pressed buttons, no result.

Just started.
I went to the left and got stuck.
10/10 would buy DLC

WOW!!! It took me forever to finish, but it was worth every single second. Nice ending btw.
