This game is really well made. The mechanics are intuitive yet the puzzles are complex, and the artwork is simple yet effective. Other details like the responsiveness of the blocks makes the game feel very polished. I also really liked the music and how the motif stayed present throughout the game but the vibe was different for each level.
The final section was painful but it felt really satisfying when it paid off in the end. I do wish there was a little more breathing room during the quicker sections, though.
