Great free game
This game is an amazing game to pass the time, completely free, and also simple to learn hard to master. Not sure how many levels, and maybe they could add an endless/time mode so that you have to do as many as possible in like five minutes or something.Guy number two
Fun, calm, unique
It's a nice little game! I'd like if there was a bit more variation to the music although it's a good tune. Nice job though! Very pleasing game with a little challenge.La.chaleur
Needs a ten star option
It REALY is free but I'm getting a card to pay 2.99 for it keep it up addive as hell as a musicianBaby-Penguin
Amazing!
This game is amazing. It's a super simple puzzle about adding waves to create a certain product waves. You don't need to actually know any of the math or science behind it to understand how to solve the puzzles and the game is very easy to learn. And there aren't any ads which is rare for a free game, especially one this good!TrustMeI'mAPhysicist
Great & Free
This is one of those few games that are actually really fun. The concept is great, the gameplay is innovative, but the music is a little monotonous :/
I'm also really happy because I want to see more apps like this that allow you to pay what you think it's worth. Great job guys!42nd St. Magrathean
Enjoyable, but only minimally challenging
This is an interesting concept and an enjoyable means of passing the time but there aren't enough constraints to really call this a "puzzle", IMHO. If you're just looking to kill a few minutes you could do worse, but I wouldn't turn to this if looking for anything more gratifying than that.mxtylr
Great game
This is a great 5 star game that should be worth at least 99c but I am too broke for that.
Great game for passing time in the cardylan2546
Addictive
Hard enough and easy enough to make it painfully addictive.Kayla Bayla
Very Unique Game
This game is oddly unique, but in a good way! I haven't seen anything like it, and I just had to check it out! It is relaxing for me, with no ads, and you play at your own pace. I would recommend it for those of you who are looking for a "relaxed playing game". Good job on this one!!Luharpoo
SO much fun
I definitely thought the first ten levels were ez but then it got so fun and interesting, I will play this game until the end of timejen_jak
