Epigraph has been a joy, especially when you consider that it's only $3.

I love puzzle games like Portal, The Outer Wilds, Etc., but when I try to explore further in the genre, I often struggle to find many that provide a sufficient challenge.

I found that Epigraph, while short overall, provided a solid 4-6 hours of playtime.

The goal in the game is decipher a series of stones and tablets containing a totally unknown language.

The Zachtronics games are also phenomenal and probably even more difficult overall if you're like me and looking for a challenge.
