More moments in this game live rent-free in my head than pretty much every other RPG Maker game I've played, and they have since I played this game like, what... six years ago? Went back for another playthrough recently, and it's definitely hitting different now that I can pick up on so much more of the subtext. There's so many details to appreciate, too, even outside of the writing. Art's great, music's an unrelenting series of jams (and/or very good at setting the vibe), and the gameplay itself is your classic turn-based RPG fare, with a few fun twists thrown in there to keep things spicy. The post-game is also pretty robust, and insanely hard, imo. Good amount of challenge for the kind of folks who like to go nuts with build-optimizing (which the game gives you a pretty wide selection of options for). If I were to try to criticize anything, I'd say it's a little on the grindy side at times, but that has its appeal for the more hardcore types. Easy mode does exist, though, if you're not all about the grind; all it'll do is increase money and exp rates, if I'm not mistaken. All in all, guh-reat game, top shelf. It warms the heart, socks the gut, and chills the blood, and it does it all without becoming a tonal mess — which is rare these days, if that ain't my bias talking. If you want a good, meaty RPG with a well-written story that'll make you feel a couple things, I couldn't recommend this game more.

everytime i wake up and start screaming for about an hour because of how many fans this game doesn't have. The combat is a great mix of archetypal and unique, the story is heartbreaking in a perfect way, its funny, its fun, the musics so good, the games so good, play this game NOW. would you like me to repeat that?

I thought this was a spiritual successor to earthbound, but it's more than that. It's a heartbreaking gemstone. Jimmy deserved better, but sometimes you can't stop something that's inevitable. :(

Altered the course of my life and my relationship with the friends I watched and played alongside forever, no exaggeration. Tied for my favorite game of all time. Everything about JatPM just hits so perfectly in a way that's hard to eloquently described. The music is fantastic and fitting for every area and dungeon (Parabolic Smile is probably my fave); genuinely the only song on the OST I can say I dislike is from the Mad Queen's nightmare dungeon, and that track is MEANT to sound off-putting and discordant. Still succeeds at setting the mood. Let me come back to this when I can get my thoughts together because this game deserves it. 10/10 lifechanging experience

jimmy and the pulsating mass is beautiful beyond belief. criminally underrated among its quirkyindieearthboundinspired-rpg contemporaries, it delivers fantastically in storytelling/writing and gameplay. I find myself drawn to its realistic depiction of family dynamics, of which I can say little without spoilers. humor is pointed and inexplicably fresh. jatpm squeezed laughter and tears out of me several times, sometimes within moments of each other. combat isn't over-complicated and provides ample room for strategy. puzzles within jatpm tend to rock as well. I would have to agree that the game is lacking in visual artistic direction, which is more of a byproduct of games in its genre tending to be outstanding in that department and less of a lack of effort (evident from the charm oozing from plenty of the artwork). kasey ozymy does a fine job with battle sprites (even if some of them are a little vile), and overworld character sprites vary from solid to great. music is surprisingly high-quality, if amateur. a solid amount of the ost is just excellent music, with high-highs and medium-lows. one would be surprised by how enjoyable the sound design is. overall, the game is unpolished artistically, but still manages to have an incredibly appealing presentation. strong contender for "most underrated game of all time", jimmy and the pulsating mass deserves the world
