A robot. A signal. A planet at risk.
Centuries after the alien technology that once protected Earth was forgotten, a deadly solar storm looms on the horizon. When a faint signal reactivates a long-dormant defense system, only one machine responds.
Meet BOB — a self-aware, surprisingly snarky robot with a mission: recover scattered crystals and reactivate ancient planetary defenses before it’s too late.

Built with the Community, by a Solo Developer
Bob’s Crystals is being developed by a solo dev — yep, just one person handling the design, code, art, writing, and way too many cups of coffee. Early Access is an important step to gather feedback and keep the game growing in the right direction.
Development is ongoing, and areas currently being explored include:
Expanding the number and variety of levels
Introducing new puzzle mechanics to deepen gameplay
Iterating on the Marker Crystal Defense mode with potential new enemies and upgrade ideas
Adding more voice lines and narrative moments
Improving visuals, performance, and overall balance
There’s no fixed roadmap or guaranteed features — just a continued effort to improve and expand the experience with input from the community. If you enjoy quirky puzzle-platformers with attitude, come be part of shaping Bob’s Crystals.
