About this game
Wave Function is a retro-styled, high-tempo FPS Bullet Hell game. Players step into the role of Player Zero , facing a 100-level gauntlet inside a tight, claustrophobic simulation chamber. Each level introduces new enemy wave patterns that test reflexes, intuition, and fast decision-making skills. The minimalist yet threatening atmosphere, supported by neon grid patterns, creates a striking digital-world aesthetic. The challenging gameplay structure, dynamic hit feedback, and continuously rising tempo make Wave Function a “easy to learn, hard to master” experience. Key Features: Fast-paced FPS bullet hell gameplay Increasingly difficult enemy waves across 100 levels Story-driven progression with impactful monologues Major encounters with the final boss Two alternate endings shaped by player decisions Retro-cyberpunk atmosphere enriched with neon grid visuals Minimalistic, fast, and fluid control mechanics
