Tri Hearts

Tri Hearts positions itself as a spiritual successor to The Lost Vikings, transplanting that classic multi-character puzzle-platformer formula into an adult-oriented fantasy setting. You control three distinct characters—Gratia the priestess, a cow girl, and a cat girl—each with unique movement and ability mechanics that you'll need to coordinate to navigate dungeons and reach the exit gate. The premise leans into dungeon-escape fantasy: demons have invaded, and your trio must rely on their complementary skills to survive.

Gameplay revolves around spatial problem-solving across side-scrolling levels. Character swapping (handled via spacebar) is central to progression; you're constantly managing three separate entities with different strengths and limitations, positioning them to unlock paths that no single character could manage alone. Alice Hearts has iterated from an initial playable build to this demo version, refining pixel art assets and replacing placeholder graphics—a sign the studio is treating the project with iterative care. The HTML5 delivery means accessibility across browsers, though performance may vary depending on implementation.

The adult content manifests primarily through character design and narrative framing rather than explicit gameplay interruptions. The studio signals this is a "lewd" experience without crossing into graphic depiction, keeping the focus on mechanical puzzle-solving. For players comfortable with mature themes in their platformers, this sits alongside titles that blend cheesecake aesthetics with legitimate level design. Bear in mind this is a demo; the full experience remains patron-exclusive, so expectations should calibrate accordingly—this is an opportunity to test core mechanics and visual direction rather than a complete experience.
