Very cool idea with a lot of potential! I found it a little too easy just to spam the extending rectangular shape to win. I would love to see this developed further with some balancing tweaks. Well done!

Yes. You are Right, but so that's why I add challenges, which are not very visible in retrospect. You can open them by clicking on button next to tutorial. And there is list of challenges how you can play game. And most of them are very hard. By clicking on one of them will show you how to earn them.
