Yes, the colors are a little bit confusing. I should've changed them somehow.
Did you read the score tab in the info panel? I described most of it in there. It's a little bit confusing. And since I couldn't add any visual feedback it's a bit hard to tell what's matched.
That's a cool idea. It didn't cross my mind. XD
And yes I know. My first and only target was webgl build. But the build was giving me a lot of errors. Mainly because browsers can't read local files. Reading a pretty big json is a core component of the game. So yeah. And by the time I fixed it, the deadline ended and updates were closed :(
Thank you for the feedback!!
