Great puzzle, Joe. I like the shading, even though it meant a tough solve (for me anyway).#3: Eric (kelalatir) on Nov 15, 2025 [SPOILER]
Great puzzle!
The shape started looking familiar, until it finally crystalized into the Half Life logo. I spent many an hour on that game, and on it's recent remake, Black Mesa.
