Topic, Level "Tetris Blocks", game "BLockoban"

  Very good job of editing. I am really impressed. This is a much better level now. 5/5

  It's possible :)

  is it good enough i don't know of this is possible but i can't solve it because, I'm not that good BB player.

  I have a level almost identical in my design file. Looks like you got yours submitted first, and beat me to the punch.
The level is fine, but I would like you to take another look at it and see if you can increase the difficulty by removing parts of the walls of the box and still keeping it possible.
