8 of 15I love this game! I really like the design and minimalist design. Some puzzles are super hard and some are pretty easy, but that makes it so you don’t get too bored or frustrated. I did get thru all the puzzles in just a few days. I only wish it was longer, hopefully they come out with more packs to add to the library of puzzles.
I would play this game on and off for few years; take breaks when I got stuck but always came back to. Finally beat all levels. Found the background music to be mellow and relaxing.
Like tangram puzzles but with the pieces changing as they overlap. Stays good even on repeated plays.
This game is so good, it deserves a T2-esque sequel.
Good, creative game. Controls a bit sticky at times. I want more l"CHALLENGING levels. All in all, I liked the game. –Selffive
Fun; great, but sadly only 89 levels kinda expect more levels and some higher difficulty.
It's hard not to compare this game with Zengrams; voi is similar in concept and similarly satisfying (though not quite as challenging overall). Like Zengrams, there are no in-app hints or level skips, so there is the possibility of getting stuck. However, the number of moves is not limited and the pieces never "fuse," so you're free to fiddle around as long as it takes to find the solution. There are some cleverly designed puzzles here, but nothing quite a devious as the best of Zengrams'. Some toward the end were disappointingly easy. Looking forward to more in future updates.
This game is gorgeous, user friendly, and a real pleasure and challenge to play. Hits all the right spots for me. However, there are no settings within the app so you cannot turn the sound off. I like playing games while commuting and listening to podcasts, and with this game you cannot listen to anything else while playing. That’s the only reason for 4 stars instead of 5.
