The game is a spinoff of Windmill’s Happiness! visual novel game, and features matching puzzle gameplay where players attempt to match sets of three blocks to clear them while more blocks appear.
The game features a Story mode, an Endless mode where players continuously fight against opponents, and a Versus mode for competing against other players.
ARES Inc. released its Happiness Drops! spinoff puzzle game on PC via Steam on December 26.
Windmill’s Happiness! visual novel shipped in 2005 for the PC, and inspired a 12-episode television anime of the same name in 2006.
