Thank you for playing :) and sorry for the late replay. There are 7 levels. Was there a bug/error in the third level? To win the third level you have to move down, right then use 2 repeaters and then move to the right 2 times :D
My bad. I thought than in level 3 I got to the finish cell. And when I saw the message "you made it to level 3" and game starts from the beginning I thought that it's the end. :)
It would be great to not punish player for the single error so much, and just restart current level.
