I'm really thankful that people like my game, however it is dead. A few years ago I tried improving it but messed it up too much and don't have a backup of the project files from the state of the latest release. That means I would effectively have to redo the game from scratch.
But fear not, there is a new game coming out on Steam that seems quite similar: https://store.steampowered.com/app/4876650/Never_Sort_By_Color/
