16. Diplomacy is Not an Option: Shareware
A free demo-like release offering a taste of the full strategy game. Players defend their castle against hordes of enemies, balancing economy, infrastructure, and war.
Well-balanced difficulty and solid performance.
17. Double Down
A noir puzzle adventure where you investigate crimes using a mix of logic puzzles and blackjack-style decision-making.
Well-written, with a good sense of mystery and mood.
18. The Mr. Rabbit Magic Show
A surreal mini-platformer set during a bizarre live show hosted by a nightmarish rabbit.
Strange visuals and quirky humour define this very brief but memorable game.
19. Banshee
A short horror stealth game where the titular banshee stalks you through a dark mansion.
You’ll need to avoid detection and find your way out without being caught. Simple but effective.
20. 12.12.25
An abstract, narrative-driven game that leaves much to interpretation.
Sparse dialogue and post-apocalyptic environments build a quiet but disturbing atmosphere. For fans of experimental storytelling.
While May 2025 may not have delivered any major free-to-play blockbusters, the volume and diversity of smaller, often experimental titles has been notable. From haunted forests to digital speedruns, this month’s offerings reflect a healthy creative variety within the indie space. For players seeking new and free experiences on PC, Steam continues to be a reliable platform and these 20 titles are a great place to start.
