Goscaku

Goscaku is a top-down motorcycle game on a three-lane highway. Seen from overhead, the bike shows its wheels, coloured frame and tank, handlebars and a helmeted rider, with a headlight cone thrown forward and the road markings rushing down at you.

🎮 HOW TO PLAY
You steer with two on-screen arrows at the foot of the screen, each press shifting the bike one lane. There is no swiping or tilting — the arrows are the whole control scheme. The road throws three vehicle types at you, with the same chance for each. Red sports cars hurt most at 25 health, blue vans take 20 and the green-cabbed white refrigerated truck only 15, but the truck closes on you twenty percent quicker. Vans are a timing puzzle — they only damage you while the rear panel is showing, which toggles on for 0.8 seconds and off for 1.5, so the same van is harmless half the time.

⚡ GAME MECHANICS
The health bar starts full at 100; empty it and the run is over. Every three to seven seconds the game rolls for a bonus and releases one seven times in ten. The four bonus types share equal odds — a white first-aid kit restoring 20 health, a coin stamped 1 for 100 points, a coin stamped 2 for 200, and a blue shield worth five seconds of immunity. Every thirty seconds the difficulty goes up by one, pushing the traffic both faster and closer together. Traffic starts around 220 and keeps accelerating as the ride goes on, while the gap between vehicles shrinks from about 1.4 seconds and carries a small random jitter so the pattern never becomes predictable. After any hit you get 0.8 seconds of grace, and the offending vehicle is locked out for another half second on top.

📊 SCORING SYSTEM
Points come from two directions. There is a constant trickle for surviving, scaled by the rising difficulty, so the dangerous part of the run is also the profitable part. Coin values are 100 and 200 depending on the face, which is usually enough to justify crossing a lane for one. Damage never touches your score — only your health bar. Bonuses collected are counted separately from points and reported at the end of the run.

📱 FEATURES AND STATS
Play, Statistic, About and Exit make up the menu. On screen during a run: the Health bar and its value, Score, Time, and the left and right arrows. A Shield Active indicator appears for as long as a shield is protecting you and disappears the moment it lapses. Run Complete closes each ride with Your Score, Survival Time and Bonuses Collected, and adds a New Record line when you beat your previous best. Run History keeps a dated line for every ride with its score and duration, and can be wiped with a Clear History button. All of it stays on the device — no account, no upload, no server.
