Buried Treasure is a website created by John Walker. It's about (hidden) indie gems. I'll be honest about it: reason I found out this site exists, is because my game was reviewed there. Nonetheless I check it regularly to see which games pop up. Here are three examples I really liked. Be sure to check the rest as well.
Probably already played by anyone who reads this anyway. But first time I saw this game was on Buried Treasure. Then found out it was by the same person who made "HOOK". It's a minimalistic/relaxing puzzle game.
