Compare JEF prices across trusted key stores and find the best deal. Developed by Akupara Games. Published by Jeremy Couillard. Released on 2/28/2020. Available on PC. Genres: Action, Adventure, Casual, Indie, Simulation.

A lo-fi action-adventure about a sentient jellyfish navigating an underwater world, oddly meditative for something this weird.

I picked up JEF expecting something precious and indie-quirky, and that's pretty much what I got. You play as a jellyfish drifting through hand-drawn underwater environments, solving simple puzzles and avoiding or defeating enemies with deliberate, slow-paced combat. The whole thing has the vibe of a storybook come to life, zero stress, zero timers, just you and the ocean. What works is the aesthetic and the chill pacing. What doesn't: the combat is functional but forgettable, and the puzzle design rarely pushes beyond "move block, open door." It's a game that knows what it is and commits to it fully. If you want a short, peaceful experience that doesn't demand reflexes or strategy, JEF delivers. For everyone else, it's a hard pass. Alex, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
