I can’t open the last level. Why?

We are always working on improving the game and adding new content. We want to give you the best experience ever, that’s why we carefully think, program, and test our games in many ways. But because of that, sometimes providing new levels may take some time. You can see that the next level is “Under Construction” (you can recognize it by yellow tape and a green “Coming Soon” sign). Rest assured that we’re working hard to release new levels as soon as possible. Your patience will be rewarded!
