Editor's Notes
A legendary mega-crystal waits 3000 meters into the cave, and your LAMP is the only thing keeping you going
What players will love
- The lamp drains continuously, so prioritize a steady chain of supply pickups over playing it safe
- Each hazard knocks 15 off the meter; sidestep them rather than trying to power through
- Speed ramps up as your distance grows, so the back half of the run is the hardest part
- Set up your position for each pickup a moment early to avoid clipping a nearby hazard

About Cave Spelunker
A legendary mega-crystal waits 3000 meters into the cave, and your LAMP is the only thing keeping you going. The view scrolls steadily ahead while you slide left and right, scooping up the yellow supply pickups that refuel the lamp and steering clear of the red hazards that drain it. The lamp meter starts at 100 and ticks down constantly, so you cannot just coast; every supply you miss brings the run closer to ending in the dark. The deeper you press, the faster everything comes at you.

How to Play Cave Spelunker
You move forward on your own; shift left and right to catch the yellow supply pickups, which each refill the LAMP meter (by 15 to 25) and add 10 points. The red hazards cost 15 off the meter on contact, so dodge them. The lamp drains the whole time, and your distance also adds to your score. Keep the lamp above zero until you pass 3000 meters to reach the mega-crystal.
Controls
Left and right only: arrow keys, A/D, or tap the left or right third of the screen. Space starts the game and restarts after a run.

Frequently Asked Questions
How far is the run?
It is a single 3000-meter descent. Pass 3000 meters with the lamp still lit and you reach the mega-crystal; let the lamp run out first and the run ends.
Can I climb or move up and down?
No. You advance automatically and only control left and right movement, so positioning across the lane is the whole challenge.
