About Super Slime Surfers
An online team shooter in the browser played on a small planet. In team matches two teams try to cover more of the planet in their slime than the other side before time runs out (a Free For All mode, where you pick your own slime colour, is also offered); you collect stronger weapons, splat opponents to swing territory your way and recharge slime faster while standing on your own colour. Pressing E switches between walking and surfing, surfing on your own slime is faster, and mashing the arrow keys in the air performs tricks such as double backflips. Team colours are assigned automatically and a leaderboard tracks players. The entrant pitches it as “Splatoon meets 1080 Snowboarding”. It was entered as Slime Surfers; the live page is titled Super Slime Surfers. It was made for the Cursor Vibe Jam 2026, whose rules required at least 90% of each game's code to be written by AI; the official submission lists Codex as the tool. It finished 373rd of 945 entries. Free in the browser.
