Stellarea

Looks like i probably ended up quitting at the same level Haze01 did. I tried various attempts at first then eventually ended up trying to make each individual glass add up to the same number of corners, but that didn't work. After that I also tried grouping by various criteria simultaneously, like spin direction at bottom left, odd numbered corners on top, and color groups at bottom right, which also didn't work. I don't particularly feel like brute forcing it however, so i'll just leave it be.

Played on Chrome.  It took me longer than it should have to realize that I can click and drag on the stars; my first interactions were just clicking and noticing the sounds being made.  I soon discovered that the itch.io page overlay (with links to view the creator's other works, follow the creator, etc.) interfered with my ability to move stars in the upper-right corner, but I was able to get around that by scrolling the page a bit.

I don't know how many levels there are or how many I cleared but I got stuck and gave up.  The level I quit on featured three lenses that all overlap to make seven partitions and the level has seven stars: four rotate clockwise, three counter-clockwise; there are five colors amongst the seven stars, split as two pairs and three singles; there are similarly five shapes, split as two pairs and three singles.
