I don't think I've added to my GOG Wishlist in a long time. But since I did it for Steam let's find a few on sale games to add.

Felix the Reaper ($3, 88% off) - I keep mentioning this puzzle game.

Beholder ($1.50, 85% off) - A weird mystery game.

Distrust ($1.80, 85% off) - Don't think I've seen this one before. An isomorphic survival game set in the Arctic and having randomly generated levels.

Terraria ($5, 50% off) - an open-world 8-bit side-view adventure game.

Neon Chrome ($5.25, 65% off) - top-down cyberpunk-themed shooter.
