Nice job Isa!
Puzzle 1: Took me a second to figure out the goal, but was clear from experimentation!
The highlight that shows which tile you have selected is a bit in the way when trying to see if everything fits together, I wonder if there's another way to highlight the tiles?
Puzzle 2: oh man I'm horrible at this one. The root setup makes it hard for me to have a good idea of what belongs where, so I keep just messing it up and feel like I'm not making any progress. I didn't finish this one.
Puzzle 3: Nice, straightforward even though it takes me a long time to get everything right: I clearly am making progress here. Because it took a while the music did start to annoy me at some point ^^'
