A good idea.
It was a good concept but unfortunately it just didn't live up to its potential. The movement was a little tricky to get to grips with but if you persevere it's worth it.
Full marks for the concept.
Unfortunately you go down to 5/10 for the execution of the plan. After you complete the maze you get two marks of 'instructions' with the one on the left restarting the game. The biggest downside I found, though, was that as often as not I was left with a blue vall on the line and a red ball floating in midair with no way to reach it.
To sum up: with a bit of fine-tuning this could become a very good game.
