Project Solaris is a story-driven roguelite RPG where you guide Solaris, a struggling mage, through a transformative 100-day journey toward becoming a true sorcerer. Accompanied by her loyal familiar Homu, Solaris must navigate trials on her island home while gradually uncovering a deeper narrative through an achievement-based progression system. Each playthrough reveals new story threads and character sub-stories, with multiple endings determined by your choices and playstyle.

The core gameplay loop revolves around strategic daily decision-making. Each day, you select three activities from five options: Combat, Social interaction, Shopkeeping, Development, or Rest. These choices directly influence character relationships, story progression, and your combat readiness. The map evolves every 20 in-game days, introducing elite battles on Day 10 and culminating in the "Trial Ceremony"—a boss battle that tests your preparation and strategy.

Combat emphasizes synergy between Solaris and Homu. You control Solaris while commanding Homu through quick-time events (QTEs) that determine skill execution success. As your bond deepens, difficult QTEs become easier to activate. Homu learns skills from randomized options each run, encouraging fresh tactical builds. Solaris crafts weapons to complement Homu's abilities, with buffs and debuffs creating dynamic combat scenarios. Resource management is critical: earn money through battles or shopkeeping work to purchase expensive Solaris equipment or craft cheaper, randomized gear for Homu.

What sets Project Solaris apart is its narrative-forward approach to the roguelite genre. Rather than treating story as secondary, the game weaves character development and plot revelation into the roguelite structure itself. Your repeated playthroughs gradually expose the full picture behind Solaris's journey, with different story paths emerging based on your decisions. The pixel art aesthetic combines with charming character interactions to create an engaging, character-driven experience that rewards both strategic mastery and narrative curiosity.
