Field Day is a free-to-play adventure game developed by Liam Games, available on Android 9.0. As part of the developer's hobby, this game is a simple athletic meet horror game. The objective of the game is to collect gold faces while running away from big faces. The game is available in both Japanese and English languages, and the language setting of the app determines the language used.

The game's content is straightforward, with the player running around collecting gold faces while avoiding the big faces. The game's features include horror, athletic meet, and town horror themes. The game was developed using Unity, and the developer used various tools and resources such as BGM from MMT38, sound effects from Tamatemu-sama, and an enemy model from Makehuman. The development period was a few days, and the game has been updated to fix a bug that caused unresponsiveness when pressing buttons.
