Switching between the three shapes stays interesting the whole way through, and I like the little extra layer of rotating with the scroll wheel; a little small detail that added depth. The way new mechanics are introduced is handled well too. Each level builds on the last, and the puzzles feel thought-out without being overwhelming. That final section where each path leans into a specific form was a good finish. Clean UI, chill music, good puzzle design. Nicely put together.
