What it does
- Lives on your desktop — a transparent, always-on-top overlay that stays click-through until you hover a slime
- Typing feeds it — keystrokes are counted, never read. Typing earns jelly to spend
- 60+ species — gacha pulls, rarity tiers, daily/weekly bonuses, a dex to fill
- Breeding — cross species into one-of-a-kind hybrids born as babies (pacifier included)
- Personalities — 16 psych types; slimes perch on your window tops, nap on cushions, hide in boxes, dangle from your cursor
- Decorate — furniture props you can place and drag: bowls, cushions, plants, speakers, mirrors
- Photo mode — pose and snap shots into the album
- Pomodoro — optional focus/break timer the slime runs with you
- Weather — optional ambient weather on the ranch
- Interact — drag, throw, tickle, pet, toss treats (right-click the cookie to pick the snack)
Privacy
- Keystrokes are counted, never read — no content ever leaves the key counter
- No account, no ads, no tracking, no analytics
- Purchases are server-verified Ed25519-signed grants bound to your anonymous install ID (
JP…) — no email required
