The Harvest Grove Fall Festival is supposed to be a time of autumn delights—hayrides, caramel apples, and the biggest celebration in town. But this year, something’s not right.

Someone has been playing pranks all over the festival. At first, they were harmless enough, but now, people are getting hurt. And you can't shake the feeling that someone is constantly watching you...

As amateur sleuth Marcella Moon, you’ve been called in to uncover the truth before the festival is shut down for good.

Gameplay Features

Investigate the Festival – Question quirky staff members, explore the festival grounds, and enjoy the halloween festivities.

Gather Clues & Solve Puzzles – Interrogate suspects, find clues, and piece together the evidence.

A Voice-Acted and Animated, Immersive Mystery – A cast of colorful characters brings the festival—and its secrets—to life.

The clock is ticking, and the festival’s 50th anniversary may be its last. Can you solve the mystery before the grand finale? Or will you fall victim to the Phantom of Harvest Grove?

This is the 6th game in the Marcella Moon point and click mystery series. The games can be played in any order.

🎃 Note About the Demo 🎃

This is the first Marcella Moon game developed in Unreal Engine, which allowed me to add facial animations and high quality visuals. However, it’s also more graphically demanding than my previous five Marcella Moon mysteries — which all run smoothly on a wide range of systems, including lower-end machines.

If you’re experiencing lag or technical issues, it may be due to your system’s specs or graphics settings. Don’t give up! You can still enjoy the rest of the full Marcella Moon series, which is built in a lighter engine and optimized for broader performance. You can also try the tweaks listed in the discussions page to try to get the demo running on your machine.
