Nice job on this. Art and music are nice, but it’s a bit hard to tell the tiles apart visually. I felt like half the puzzle was just trying to visually locate elements, rather than solving the puzzle itself.
Consider using the first 1-2 levels to teach about mechanics. Eg - show that you can trap yourself with a flower, or something.
The floor buttons could probably have just been regular buttons, since in almost all cases you could just walk over it multiple times to get the state you wanted. I’ve been playing Isles of Sea and Sky recently, and that has some interesting “walk over” puzzle mechanics that might be worth checking out.
I enjoyed the puzzles. The later ones did a good job of making you plan your path ahead of time.
All in all I really liked this game. Well done.
