(I have a lot to say about this game lol, sorry about the paragraphs of feedback :) )
There is a lot in this game that makes it great. The intro animation for the title screen is amazing, the UI in general looks great, the art used for the game looks very appealing and the game being as complex as it is very impressive to see in a 2-day jam.
I feel that the core rules and mechanics of the game are a double-edged sword. On one hand, its very original and if one were to learn the mechanics, it would probably be a very in-depth game to play and be fun to master. On the other hand however, as it is currently it's very hard to just jump in and play this game since you pretty much have to read over every rule to understand what to do. There's also just so many rules that I don't really understand what to do (perhaps I'm just too small brain). I feel like if the game were to slowly introduce more tile types as the game goes, it would be easier to learn the core mechanics of the game as it goes on.
Although the sound is great overall, sound effects for selecting tiles, and for when some tiles changing the board around would add a lot. Its usually hard to tell what's happening once I select a tile (again this could be because I didn't quite get the rules but oh well). Also having some form of game over music or sound effect would be nice to have as well.
Lastly, there were a fair amount of bugs that happened during my time playing it. In addition to the ones addressed previously, I also sometimes had my game completely crash upon selecting a tile, with itch.io giving me an error message and all. Not sure if this was an itch problem or a problem with the game, but it happened to me twice nonetheless. Also a small thing, but the Quit buttons completely freeze the game after their clicked. I know that this happens due to how Application.Quit() works in Unity though, so I think just omitting them from the web build altogether would have been fine.
