What HN said
What people liked
Clean, minimalist execution and satisfying interface
From 3 comments
Very nice and satisfying, but I would suggest ramping up the difficulty a little faster. I got until lvl 15 by just flipping the obvious areas, taking no more than 2 seconds.…
BoppreH on HNReally nice concept and super clean execution. Wish I’d had 1/2 this restraint on adding complexity when I made my own tile-based puzzle game[0] [0] https://www.hidden-mirrors.com
james_marks on HNHad a lot of fun with this, great job on the concept and presentation!

Level progression teaches patterns well
From 2 comments
I really love how the first few levels teach you about various solving elements and patterns. very well done.
zem on HNDid I just get flipped in level 13? I really like it, the level progression feels good. Very nice execution.

Fun concept that builds pattern recognition
From 1 comment
I like it. Played a bunch of levels. I could feel my brain learning new patterns (like the card game Set). There are a handful of really useful primitives.

Objections
Difficulty ramps up too slowly
From 3 comments
Very nice and satisfying, but I would suggest ramping up the difficulty a little faster. I got until lvl 15 by just flipping the obvious areas, taking no more than 2 seconds.…
BoppreH on HNThe game is quite fun. But it seems the difficulty ramp quite late? It's not very difficult to get the answer with least step by solve the side first until about last 20 levels.…
mmis1000 on HNI agree the ramp up is a bit slow, but I love the concept, and the interface. I am stuck at level 26 edit: found a way to solve it in 6, but not in 4

Par value is too big a hint; hide it
From 2 comments
Love it. The “par” value is a huge hint. You might consider hiding it
stephenlf on HNPlayed until 27. All the levels were pretty easy, 15-30 seconds per level. Mainly because of the "par" feature

Difficulty spikes suddenly after easy start
From 1 comment
This was incredibly easy and then it suddenly got incredibly hard

Android back gesture interferes with mobile play
From 2 comments
Android gestures need to be prevented in order for the game to work on mobile (drag finger from right to left go back). Nice game thought.
atum47 on HNWorked fine for me on Firefox on Galaxy Note 20. I've never run into single finger back gestures that can start anywhere - seems like that would break almost everything that…

Requests
Add daily levels
From 2 comments
Great game, thanks for sharing. Would love to have a daily level.
slig on HNThanks for replying. Since you're considering bigger levels, maybe three daily levels: easy / medium / hard. On my games I usually go with five levels [1], in different tabs that…

Show par on result screen with try again option
From 1 comment
I think if you make the par visible in the "result screen" and add a "try again" option to "next" this could make it more interesting without the need to ramp up difficulty. I…

Questions
How is the solver or par computed
From 2 comments
If anyone wants an extra challenge: think, how would you write a solver for this?
bogdanoff_2 on HNSo what is your solution, I'm curious. Regarding the number of solvable boards. It is actually possible to calculate the exact number. The solvable boards correspond to the image…

Nice job. I'm reminded of the "Lights Out" game [1]. https://en.wikipedia.org/wiki/Lights_Out_(game)
