TUNL - Cave Flyer

TUNL is a one-button, hold-to-thrust cave flyer: hold to climb, release to fall, and see how far you can push into a procedurally generated tunnel before the walls close in. Key features: - Physics tuned so climbing and falling feel perfectly balanced, not floaty or twitchy - Five distinct coin power-ups: gold widens the corridor, blue slows time, red shields one hit, orange grants ammo, green pulls coins toward you - Real triangle-shaped stalactite hazards with accurate collision, not sloppy hitboxes - Difficulty that never truly plateaus: it ramps hard over the first couple minutes, then keeps intensifying for veteran runs - Daily seeded tunnels with rotating archetypes (Chicane Day, Mine Gauntlet, Coin Rush) so every player faces the same challenge each day - Persistent shard currency and ship progression that carries across runs, with prestige tiers for long-term players - Daily and all-time leaderboards, milestone bursts, and near-miss/combo bonuses that reward tight flying, not just survival What makes it different: most one-button flyers get boring fast because the difficulty caps out. TUNL's scroll speed keeps climbing indefinitely, so a long run is never just endurance at a fixed pace, it is a genuine skill ceiling. Real outcome: casual players can expect to comfortably clear a score of 50-100 within their first few tries. Pushing past 233 means surviving the tunnel at full difficulty, and top players keep chasing higher scores as the game scales without limit.
