A decent little puzzle game with nice minimalist visuals and sound design. Every block makes the sound of an instrument (like harps, guitars, and snare drums). It's a relaxing puzzle game, but not an engaging one. Many of the puzzles are more about finding awkward angles rather than engaging with the actual level design. This makes a nice game to play when you're bored, but not much else. It also has the most ethical monetization I've ever seen. You choose what to pay. Which deserves kudos.

very very addicting game. as a music major the sounds are music to my ears, and i can easily make it through several tens of levels without ever realizing that i was doing something else. its quality of being ad free also makes the game flow smoother than a river. the pay-what-you-want model is incredibly generous and the way it doesn't force you to pay anything makes it different from other games (if i wasn't broke i would absolutely pay something for it). philipp you are a miracle worker

130+ levels in, I like the concept of the game and that there are no ads unless you want to get a hint. But i dont really like the level design. it starts out by being intuitive, you still gotta think about it, but the patterns make sense. But as you progress, the levels make less and less sense, and it goes from "let me think about it" to "let me shoot a 100 balls and see what happens".
