Okay?

If only we lived in a perfect world, then every game could be like this one. Pure, pristine puzzle action completely free of charge with no forced ads. Sure, it is a little frustrating when you watch an ad and you don't get a hint, or when you reach a level where the one hint doesn't help because there are so many things to bounce off of, or when touch controls are too imprecise to perform the solution, but I think it was well worth my time and never overstayed its welcome.

I finished it by using hints just 3 or 4 or 5 times. Likely 3 times, as the hint sometimes got pressed accidentally (likely I didn't even need hints, but hints motivated me), so basically it ends at... Okay... maybe I shouldn't spoil it, but in short, when it gets almost impossible (when it gets boring, it ends on time, I thought there's more), it ends with... Okay. Took me 1 or 2 days. I'm still curious what social experiment were you talking about... Okay.

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.
