Hello again (I have been quite busy and am exhausted, but I finally read your detailed answer!).
Wow, you were not forced to update everything, but it is great you did! (I also have a stack of updates to implement when I get the time.)
Regarding the constraint: I may have been a bit harsh when questioning your choice. I guess I tend to expect strong twists, but your reasoning is fine. Deal.
To be honest, the real reason I chose red, green, and blue for the colors of the gems are because of the RGB color model!
This is also a nerdy reason, so I am still pleased. ;)
PS: oh, by the way, I totally forgot to speak about the installation: you packaged your game in an installer (which works well), but it appears this prevents the itch.io launcher/app to be able to launch the game directly. I am no expert on how to deal with this, but I have seen that its manual addresses this kind of issues.
Instead of shipping an installer (MyGame_setup.exeorMyGame.msi), just push the install folder with butler.
Seriously, please do. We'll do our best if you don't (see Compatibility policy), but please do.
