I’ve recently implemented the mechanics of a puzzle that seemed very interesting to me.

As you progress through the game the levels vary in different parameters. You can choose any level you want.

I added a vote after each level and I would be very grateful if you could estimate the gameplay after passing each level.

There is a version for browser and for Android devices. Links are attached below:
