Hi CrimoraDev
I really like the concept, I did get stuck on level 5 I think it was. I tried building up down the long hallway, but it seems to block me from jumping and shrinking at the top.
I also tried crossing the red pit, but was not successful. The blocks just fall into the red abyss and I tried to build a bridge, but could not reach.
The glass was also not breakable for the extra blocks.
You should expand this, it would make an excellent full game.
PS. The web version does not work very well. Anyone wanting to try this, download instead.
