Okay?

There is much to enjoy here: the minimalistic style, simple and intuitive controls, free play, ads only showing to receive hints, voluntary pay-what-you-want model. I appreciate the open communication that this game is an experiment. This lets me overlook the many random filler levels that don't involve puzzling, just trial and error. Also wait and see when things get mixed up at level 75! Love it! So why the 3 stars? I paid and still have to watch ads for hints. Now I feel cheated.

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.

Great game! The levels are not too easy, but also not too hard. There are a LOT of levels, so the game would take you a while to finish. And even after that, there are still the user levels and the custom level maker. The game has a calm and minimalistic atmosphere, which is completed with the sound effects. I would genuinely pay 1 or 2 dollars for it but can't, because I am not able to get a credit card yet. Great game and great job, dev!
