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.

Fun and addictive, yet very simple. Requires a bit of logic but very satisfying to solve all of the puzzles. There are no forced ads and you can get a hint by watching one ad. One minir complaint is that the ad it makes you watch afterwards is around an entire minute long, which I think is pushing it- but I will put up with it because the gameplay is great enough. Would recommend if you like simple, abstract strategy games.

I would like to give less than 5 stars but I do think it's closer to 5 than it is to 4 stars. I love this game. I'm just not a big fan of the few levels that aren't so much problem solving as they are brute force. This becomes a lot more common in the featured user levels. But overall, it's a great little game to pass the time. I'd love to code it into Python and generate heat maps of where you can solve every level from. Seems like you'd get some beautiful images.
