Really cool i love it :D. Yet i still think the levels should be getting harder, not easier like it was for me. :)
I chose to do it this way since the first one is very frustrating if the right path is not found. The third level was the most difficult, it became very frustrating because time was running out trying to go through the last hole. I modified the opening 2px but it became extremely easy. I was in the dilemma that the game could end or not. I decided on the second. I'm glad you liked it.
