Fossapo

Fossapo is a one-tap endless runner set in a blue night city. Your character is a grinning yellow ball fixed near the left edge of the screen; the mountains, skyline and road markings scroll toward you instead.

🎮 HOW TO PLAY
Touch any part of the screen and the ball jumps. Jumps are ground-only — there is no second jump in mid-air, so the timing of the first one is the whole game. The ten-toothed saw discs with red hubs cost 40 health in a single touch. Wooden crates with a dark X-brace sit on the road and cost 20 health if you clip one. Floating blue chips sit above the road and are yours the moment you touch one.

⚡ GAME MECHANICS
Speed begins at 8 and rises by another 4 every 15 seconds, uncapped, so a long run eventually outpaces anyone. Obstacle spacing narrows once per second and bottoms out at 45 seconds, after which only the rising speed makes things harder. You begin with 100 health and nothing in the game restores it; the bar only ever goes down. After a hit the ball blinks and ignores damage for about 0.8 seconds, which stops one bad landing from becoming a pile-up. The spawner also refuses to drop a coin and an obstacle on top of each other, so you are never asked to take damage to reach a pickup.

📊 SCORING SYSTEM
Your Win Score builds from two sources. First is pure survival: the counter rises every frame at a rate set by the current scroll speed, which rewards long runs twice over. The second is the coins, which carry face values instead of real multipliers: the 1x chip is worth 10, 2x is 20, 3x is 30 and 5x is 50. Chip value tracks rarity: 1x is the common drop and 5x the scarce one. Hits take health and nothing else — your score is never reduced by a collision.

📱 FEATURES AND STATS
The home screen leads to a menu with Play, Statistic, About and Exit. While you play you can see Win Score, Time, the HP bar, the Coins counter and a small Tap to Jump prompt. The Run History screen shows Best Score and Total Runs, followed by one dated card per attempt with its Win Score, duration and coin count. The Run Complete screen reports your Win Score, seconds survived and coins collected, and calls out a New Best Score when you beat the record. Scores are kept locally on your device only.
