this is nelly jellies, a free browser puzzle game built around a simple twist on the usual merge format.

instead of dropping pieces from the top, you launch jellyfish from the bottom and they float upward. the goal is to merge matching jellies, manage the board, and keep pushing for a higher score.

it works right in the browser on phone, tablet, or desktop, so there’s nothing to install. there’s also an android version live, with ios in progress.

there are rare jellies and abilities like flip, whirlpool, tsunami, sonar blast, and bubble up that help make each round feel different.

GemininCLI helped with a lot of the physics and gravity stuff that I'm not smart enough to understand 🙃 hope you enjoy!

finally added persistent saves to Nelly Jellies and it made the whole thing feel way more like a real game.

before this, the game was fun but kind of disposable. you could play a run, close it, and that was it. now progress persists on both android and desktop, so players can come back to their current game instead of starting over every time.

the setup is pretty simple:

• desktop/web uses browser storage
• android uses Capacitor preferences / native persistence
• the game state gets serialized into a clean save object
• on launch, it checks for an existing save and rebuilds the board
• if something breaks or the save is old, it safely falls back to a fresh game

what made it trickier than expected was deciding what actually counts as “game state.” not just score, but the active jelly positions, sizes, special jelly types, current abilities, and enough physics data to recreate the session without it feeling broken.

not the flashiest update, but this is one of those boring features that used to be horribly time consuming with a lot of google searches.. my how times have changed.

Description:
Nelly Jellies started after my daughter got hooked on the watermelon merge game with her grandpa, then told me at swimming that my next project should have jellyfish. That turned into a chill underwater merge game where you launch jellies upward, combine matching ones, use powerups, and try to keep the board under control as everything floats and bumps around. There are rare jelly types, abilities, leaderboards, and a slower cozy feel compared to most arcade puzzle games. The Android version runs best, but the web version is free and works right in the browser.

I built the game myself, but my 4 year old daughter is the lead designer, main tester, name inspiration, and harshest critic. She helps decide what feels fun, cute, boring, or worth changing.
