How to Play BULB!
Quick start
Use a light burst to inspect the first platforms. Make one safe jump, then wait for the light to recharge before attempting an uncertain crossing.
Controls
Use the directional pad to move and the game’s jump and light commands. Check the action prompts before combining a jump with another ability.
BULB! — About this game
A brief view of the platforms is an invitation to plan, not simply hurry forward. Look at where the next safe step lies, wait for another light burst if the route is unclear and avoid spikes that can shatter the fragile hero. Unlimited lives let you learn a room through repeated attempts. Build a short, reliable sequence before extending the journey into a larger area.
