Overview
CosmoBreeder Yiffai is a 2D adult exploration game for players who enjoy furry sci-fi settings with both gay and straight content available. The tone is playful and creature-focused rather than dramatic.
Story
A cosmobreeder's rescue mission ends with a crash landing on the alien planet Tutone, stripped of equipment and clothing. Armed with only a Lighttazer, the player must recover stolen gear, track down other missing cosmobreeders, and uncover what happened to them while surviving among the planet's native creatures.
Gameplay
Players explore service tunnels and forests on Tutone, searching for artifacts and equipment that grant new abilities and open up new areas. Along the way, the player tames alien fauna and breeds with them to collect biodata, with a choice of male or female cosmobreeder protagonist shaping which encounters are available.
Features
- Choice between male and female protagonist, changing available partners and scenes
- Hand-drawn 2D art depicting a variety of alien creatures
- Ability and equipment recovery tied directly to exploration progress
