The gameplay of the game is a mixed bag, with some players finding it enjoyable and fun, particularly praising its unique mechanics of "possessing" enemies and the fluidity of level design. However, many reviewers criticize it for being repetitive, lacking innovation, and becoming boring after a short period, with some noting issues like sluggish controls and a limited field of view that detracts from the experience. Overall, while the game offers a few hours of satisfying gameplay, it struggles to maintain engagement over its lengthy level count.
- “Surprisingly enjoyable, although rage-inducing, platformer with pleasant music and graphics, as well as fun gameplay to accompany it.”
- “Jelly Killer is a great little platformer, not too hard to get all achievements, interesting mechanics (where you take over the bodies of different human hosts each with different abilities to get you through the level), and a sweet retro graphic style.”
- “The solution of the puzzles using this 'parasitism' gives a very fun dynamic for the gameplay, the stages are all interconnected (which gives an excellent fluidity to the game) and the level of difficulty increases gradually which helps the player's learning.”
- “The entire game takes place in a brown and gray environment with the gameplay revolving around the same exact core concept of using your jelly to control targets and use their abilities to open a path to the end of the level where you repeat this ad nauseam.”
- “There's nothing compelling, innovative, intriguing, or refreshing to see throughout the entire game and the core gameplay isn't exciting or dynamic enough to warrant playing through its entire 54 level layout, of which its levels consist of 30 second to 1 minute long stages that you can easily cut through on your first run.”
- “The gameplay ain't fun at all, you can't turn off this music which is a 5 second loop and guns don't seem to have any pattern so if you die it's just random, pretty disappointing game overall.”

The graphics of the game are a mix of retro pixel art and cartoonish styles, with some players appreciating the nostalgic aesthetic while others criticize the bland color palette and stiff animations. Overall, the visuals are considered decent for a platformer, though the frame rate and repetitive backgrounds detract from the experience for some. While the art style has its charm, it often feels dated and lacks the polish seen in more modern titles.
- “Surprisingly enjoyable, although rage-inducing, platformer with pleasant music and graphics, as well as fun gameplay to accompany it.”
- “Jelly Killer has an art style of a 2000's flash game and I absolutely adore the art for this game.”
- “Graphics are definitely great, cartoonish but also detailed.”
- “The game has a cartoony goofy art style, the sprite quality is decent but the animations are stiff and the color palette is very bland, both for the characters and the environments/background.”
- “On top of its ugly aesthetic of trying too hard to be retro, the game assaults you with its 30fps gameplay and its 30 second loop song that drones on - yes, singular song, and its environment is just as repetitive and one note.”
- “Acceptable graphics, but poor animations (impoverished by low fps), especially the transitions between screens.”

- “The sound effects are pretty monotonous and there are barely any music tracks; they're mediocre at best, but it’s the only thing you’ll hear for the next 3 hours.”
- “The music is very repetitive and I didn't find how to turn it off, so that was annoying.”
- “On top of its ugly aesthetic of trying too hard to be retro, the game assaults you with its 30fps gameplay and its 30-second loop song that drones on - yes, singular song, and its environment is just as repetitive and one note.”

The story is generally regarded as simplistic and forgettable, with a basic premise of escaping a military base as an evil sentient blob.

Overall, players feel that the story fails to evolve or provide compelling motivation as the game progresses.
- “Actually playing it, though, was a whole other story.”
- “Nice story.”
- “Oldschool inspired platform puzzler where you play the role of an experimental sentient bio-weapon that can take control of humans, on its quest to escape the high security facility in which it is contained.”
- “After about the 15th level or so with nothing really new to discover, you're just recycling material and there's virtually no plot to convince you to stay, and the puzzles aren't that hard or challenging.”
- “The story is pretty simplistic and nothing special.”
- “The game starts with full screens of text which tell the setup of a story, which is then left behind and, as far as I can tell, never touched on again.”

stability

The game experiences frequent freezing issues, with some users reporting constant freezes on multiple computers. However, the short level design mitigates the frustration, as players can quickly restart without losing significant progress. Overall, while stability is a concern, it is somewhat alleviated by the game's structure.
- “Except there is one massive flaw: it freezes constantly!”
- “I've tried it on two different computers and it just randomly freezes in levels.”
- “While there were quite a few game freezes at random times, they didn't happen too terribly often, and the game made up for that with the stages all being really small so you never lose much progress.”
replayability

The game has limited replayability, as players report that it can be fully completed in about 3.5 hours, with little incentive to revisit levels due to a lack of alternative strategies or outcomes. Once 100% completion is achieved, the experience does not offer enough variety to encourage further play.
- “It took me around 3 and a half hours to 100% the game; it has no replay value after that.”
- “This game doesn't have any replayability, unless you want to play the same levels over again, which isn't that fun, because there is only one 'right' way to finish a level.”
