You are a giant snake living under a bunny town. Steer underground: arrows / WASD, the left stick, or drag anywhere on a phone.
Build up speed in the dirt and burst out of the ground to leap. Eat bunnies mid-air, then dive back in: you keep your momentum.
Boost (Space / Shift, A on a controller, the BOOST button on a phone) digs faster for a bigger leap.
Every bite makes you longer and faster, so you jump higher. Leap high enough and you reach orbit: low gravity, astronaut bunnies, saucers, satellites and a space station.
Your health drains all the time. Only eating fills it up, so keep hunting.
The bunnies fight back with carrot rockets, jeeps, tanks, choppers and jets. The threat level rises the longer you last.
Tanks are armored. Blow them up from below (burst out under them) or by diving onto them from above. Ramming one from the side hurts a lot. A really big snake can bite through the side, but it still stings.
Skim along the surface for too long and bombers come after you. They're fast, and their bombs blast through the topsoil. Dive deep to shake them off.
Grow big and mecha bunnies come stomping in, later giant ones. Only their glowing weak spots (marked with yellow brackets) can be bitten. Hit any other part and you bounce off and take a lot of damage.
Get truly enormous and feast in orbit, and the bunnies launch a nuke. When the countdown hits zero, the land is levelled: only deep underground or orbit is safe. After that, dropships bring down space mech warrior bunnies with plasma rifles.
Every so often there's a cozy bunny burrow deep underground (look for the blinking heart). Eating it fills a lot of health.
Catch a carrot rocket in your mouth to eat it. If it hits your body, it stings.
SCORE
Eat in quick succession for a chain (each bite adds x0.25).
Points are multiplied by altitude, and by x1.5 in the air.
Big things (vehicles, satellites, the station) are worth far more and take a few bites.
Fall back down from orbit for a huge RE-ENTRY bonus and a shockwave.
