Thank you for your nice comment!
Yes, level 10 is the last one, I forgot to add some kind of congratulations dialog on the end.
Tricky towers also was my obvious inspiration, very lovely game. And you should try making a physics based game, bevy_rapier worked really well and it was easy to get started. Up until day 5 the game didn't have any graphics at all and only relied on rapiers debug renderer, which made it super easy to prototype the game. Getting the feel and weight right took me a while though.
Unfortunately too many magnets made the physics somewhat unstable so I had to reduce the amount of effect blocks, but I definitely turned it too low.
The glue blocks glue to any block it touches, and it "hardens" once the block rested for a moment. I guess there should have been a visual indicator for that.
In the levels without height tape, you have to reach a certain block count to win.
