Example of why mobile puzzlers are often disappointing

The solutions aren’t really clever or interesting, most of the game is tapping random stuff and hoping you stumble into the solution. A good puzzle should have a have a simple solution that when you see makes you go “oh that’s smart,” and the process of solving it should be centralized around a catch. But you don’t get many “wow that was clever” moments like that here, and the level design feels like not much effort went into it. Each level should have its own interesting idea to contribute, and solving each puzzle should be the player’s way of exploring those ideas. Of the few “Ah-ha!” moments this game has to offer, most of them feel as if they weren’t planned by the level designer, and the way you solve a level depends completely on how you decide to try it. When there are a countless number of ways to complete each puzzle, how can any levels be thought out fully? So although there are some moments of actual problem solving here, overall it’s not great. If you’re looking to tap random buttons, this is for you. If you’re looking for some real puzzles check out the witness...

Three stars because I understand making puzzle games can be very difficult. And as a puzzle game maker I’ve made games that had similar issues. Keep trying!

Great and unique puzzle game! 🥚

In love with the simplicity that this game has and the look it sports. The puzzles are as simple as tap to light up the pegs, but as all puzzle game works, the difficulty escalates to where you have to think about each action you make. Something I noticed while playing is that with this game isn’t about how its made, its pretty well made, but just the design of the game makes it really easy to accidentally complete levels or just trial and error until you complete a level, which kind of takes away some fun, but is just a niche nitpick overall. Otherwise I would totally recommend this game.

Great game

Are you the kind of person who wants to push all the buttons? Then this is the game for you! Don’t let the lack of tutorial scare you away as it is intended for the player to figure it out through trail and error. If you still struggle with it then honestly this just isn’t for you. The only downside is that because all the levels are handmade there aren’t very many. (You better get on that dev, I crave more button mashing)
