After disappearing from the internet entirely due to the official website and Desura snuffing it along side Apple killing off the iOS/macOS versions due to age, you can now finally play Trichrome, the latest game from Helious developer Sean M Puckett, again. Unfortunately, it's only the Windows versions, so Mac and Linux folk are left in the dark unless a freak miracle occurs and they manage to import and fix up the project file in the newest version of Unity (but I wouldn't get your hopes up for it.) Because he's offering no support for it, it's a free download on good ol' itch.io, with the option to send him a few bucks if you enjoy it. I figured a few folks here would definitely get a kick out of trying it, but do know that there's no weird alien backstory to this one; just pure simple frenetic tile matching.
