I did an extremely annoying thing - I wrote up a post about this incredible game I found, only to find it had been a LunchTimeWaster not once, but twice. Thankfully, I managed to find a similarly awesome replacement at the last minute in the form of Colour Cleaner.
Colour Cleaner is the sort of game that makes you feel smart. I love games like that - the kind of games that barely need an explanation to begin with, slowly teach you subtle mechanics then bam, asks you to solve a puzzle that initially seems impossible, but eventually reveals itself to you.
It's a subtle art and, when done correctly, is a brilliant experience. In Colour Cleaner, it's done correctly.
You go play now.
