The graphics are cute and, coupled with the music, gives a very whimsical and light feeling to the game, making it quite comfortable to play. The sound effects are satisfying and fitting as well.
The gameplay concept is really interesting and I really like all the different mechanics that are introduced. The puzzles here aren't incredibly hard, but not easy either; they will make you think for a bit. It can be quite challenging!
I thought that, for example, the blocks that move with every shot you make was a very clever mechanic! It made things a lot more complicated than I expected, but it was a welcome challenge. The little hints that show up in the top right corner are also appreciated.
A cool touch that I noticed is that when you click UNDO, the game actually goes back in the music time as well, which I felt was a nice touch.
This game became quite intricate with mechanics that I didn't quite expect, but provided a nice challenge. It felt like a very pleasant experience. I enjoyed this!
