Sperm Race

项目介绍

Sperm Race is a silly but complete sperm-racing game built in 3 days by someone with zero coding experience. Author Jaehyun Cho had never written code and didn't even know what a game engine was — he described what he wanted to Claude (Sonnet) in Korean, and got back a single HTML file that ran in the browser. He later wrapped that file into an Android app and shipped it on Google Play (web version came out first on itch.io). The launch version packs four modes: Adventure (120 stages), Racing (3 laps around a track), Derby (pick a sperm to root for and help it win with obstacles), and Survival (dodge cancer cells for 90 seconds). Multiplayer with friends (up to 10 players in Derby, 4 in the others) was added in a post-launch update. All graphics and sound effects are drawn and synthesized in code — there is not a single image or sound file in the game, except free background music from Pixabay. It supports 13 languages and drag, arrow keys/WASD, and gamepad controls. The build story is unusually honest about costs: $20 for one month of Claude Pro (the whole game was built on the Pro plan) plus $25 for the one-time Google Play developer registration — $45 total. The author also reports the unglamorous half of vibe coding: building took 3 days, fixing bugs took 14.
