A note from the developer

Hi — I'm the solo developer behind Sperm Race.

This started as a dumb joke idea and somehow turned into 120 stages, four game modes, and twelve languages. The browser version you just played is completely free: no ads, nothing locked, every chapter open from the start. I pulled the ad gates out of this build so you could just play it.

If it made you laugh — or if Survival mode ate twenty minutes you'd meant to spend on something useful — the donation button is there as a tip jar. No minimum, no paywall, nothing unlocked by paying: just a thank-you if you had a good time. Skipping it costs you nothing, and I'd rather you play than pay.

If money's not on the table, these help just as much:

• Leave a rating or a comment — I read every single one
• Tell me which mode you liked best, or which stage broke you
• Send it to someone who'd appreciate something this stupid

Thanks for playing. 🧬
