Good puzzles. They do an excellent job of teaching new rules with a few simple puzzles. And so far all puzzles can be solved logically, though for some, it can be tough to figure out how.
Edit: After completing the game, I can confirm that there is no guessing involved. My only complaint is that there are no puzzles that involve all the rules and the difficulty of the final puzzle was disappointingly easy when compared to many of the puzzles earlier in the game.

Really good game with questionable UI choices and a really, really bad tutorial.
If you can make it past the wacky tutorial section and figure out what the game actually wants you to do it's a fantastic game. No guessing is required and everything is logically deducible. People commenting on symmetry / multiple solutions, clicking at random and memorizing the solutions etc are all brutally wrong. :)

Very relaxing and interesting puzzle game. There are times where it makes no sense, but then it just clicks and it becomes fun to solve. This is a one of a kind

I am really enjoying this game! It's sort of like minesweeper, but very calming. One critique is that the sound effects can get a little monotonous at times

Excellent game, I loved playing it, I think it's just the right difficulty : not too easy, but not so hard that you stay stuck on a level for hours. I liked that the rules/indications weren't explicitly said, it's fun figuring it out yourself with the examples.

A MUST-PLAY
First off, No lore, No dialogue, No characters; just you and some shapes with dots on it. This game includes great puzzles the get your mind racing for the solutions. And best of all, IT'S FREE. Definitely a must-play for any puzzle lovers.

7/10 Spatial deduction-type puzzle
TLDR: Most players will be confused by the tutorial here. However, if you stick with the game for a while, you will understand the controls and the goals. It's quite an elegant game, both in its presentation and the gameplay.
Some explanations for new players:
1. The circles in the upper-left corner select the color for the brush, so when you click on a black shape, the shape will get the selected color.
2. The circles inside the shapes show how many neighboring shapes have those colors. E.g. 2 red circles and 1 yellow circle on a shape mean that, around this shape, some 2 are red and 1 is yellow.
3. If there are fewer circles inside the shape than there are neighboring shapes, this means that this shape just doesn't give a clue on those extra neighbors. The neighbors' color can still be deducted from circles in other shapes, not this one.
Good:
+ free
+ stylish minimalistic gfx
+ stylish minimalistic audio. Though I'd say it would still benefit from a music track, and there is none here
+ the gameplay feels both novel and familiar. If you played sudoku or minesweeper, you already know have the correct approach here: excluding candidates based on color requirements in the neighbor areas
So-so:
+/- some areas have fewer dots than they have neighbor areas. Which means that a few of the neighbor areas are of "unknown" color in relation to this one. This would better be expressed maybe by a gray/black circle with a "?" on it, not just by absence of a circle
Bad:
- the onboarding is atrocious. Actually, I didn't understand anything at first and quit the game. Don't even remember why I re-launched it. Maybe the "very positive" rating encouraged me to give it another try. I guess not many players would, as you can see from the negative reviews
