Loved it. Really enjoyed the twist and the audio was great too. I like how the mechanic kept evolving.
The enemy AI could use some work, I'm not sure if it's intentional, but it does some silly mistakes and loses even when it doesn't have to.

Would be cool if you could develop it further, but I'm not sure where the idea can go.

Thank you very much :)
I might add some more visual clues at the beginning, but I'm trying to avoid directly telling people what to do, because I think a lot of the fun in puzzle games is figuring stuff out for yourself.

The resolution is 900x900, unless you're playing it on a phone / tablet, then it's 300x300 for performance reasons. (non-PC not officially supported)

Oh. I added a CSS "image-rendering: crisp-edges;" on the WebGL canvas more than 2 years ago, which would make the game look pixelated in fullscreen... I didn't account for fullscreen at the time, and I don't even remember why I added it to begin with, I should probably rethink that, thanks! good catch!

Thank you, I hope to solve the issue of getting stuck by having many available levels to solve, so if you get stuck on one level you can go play other levels until you eventually come back and figure it out.

It's Minesweeper, and it seems to work without bugs, so that's nice.

I almost missed the honeycomb mode, because it's in the settings so it's not very prominent. I only saw it was a thing because I saw the screenshot here.

From a graphic design perspective the game doesn't have a consistent art style, the board is minimal, but the mine/bomb is detailed with gradients, so they don't feel like the same "world". The buttons at the top (Setting + Restart) have another visual style, and the settings themselves (+popup) have a 3rd visual style. In short, this game needs some graphic design work.

Changing the theme is tedious because I need to keep reopening the settings and going to the theme tab each time I want to test what the theme looks like...

What I don't get is why spend time making a game that already exists? Unless you're making it as an exercise, in that case good job, now go on to make something original of your own :)
