Hey everyone! This update mostly just fixes all the bugs that have come up since the March update. I don't really have a full list of changes since I'm really bad at record-keeping; I'll have to get better at that. I also changed Quarters's design since someon…
Hey, everyone! As you might have heard, Jimmy and the Pulsating Mass recently got a console release. I wanted to get this version updated to match that, but it might take longer than expected, so I got permission from the publisher to put my current version of…
Hey, everyone! This is hopefully going to be the last update for Jimmy; it's been a while since the last one, so this one is mostly just a fix for a handful of outstanding bugs. As always, if you find any bugs, please make sure to let me know! Also, for those …
Hey, everyone, this update has been a long time coming. While many of you have been able to run Jimmy without any problems, some computers experienced crashes when walking in front of things like signs or trees that would overlap the player when they were behi…
I'd like to take a moment off the top to thank everyone who's played Jimmy. I've seen it here and there on players' top ten lists for 2018, and Jimmy's been getting a super positive response in general. Hopefully, 2019 will be a good year for Jimmy as it conti…
Hey, it's November, so I thought I'd update the game to address all of the minor issues that have cropped up since the last update. Some of these are bugs and some are quality of life issues. Thanks for playing Jimmy! -Analysis skill description is now clearer…
I'm excited to announce my new game, Hymn to the Earless God! It's still in development, so right now more than anything, this game needs your support! Please support Hymn to the Earless God on Kickstarter! Want to try the demo? Check out Hymn to the Earless G…
We asked a bunch of our regular writers to tell us what their five favourite games this year were. Today it’s the turn of everybody’s favourite newsboi Dominic Tarason . I’ve felt like I’ve been drowning in good games all year. Monster …
I've just updated the game files; many of these changes are fixing issues that players either generally won't run into or won't notice, but I do want to draw your attention to the first two changes. Consumable item prices are a lot cheaper now, and there's a n…
I just pushed out a new update that addresses some bugs. Most of these are fairly minor, but the big thing to note is that battle music should now loop appropriately in the mkxp version. Speaking of the mkxp version, make sure to opt into it as if you were opt…
After releasing the mkxp version, some new glitches came to my attention--mainly the black box covering the player's sprite for some players and battle bgm not looping accurately. So, I've switched the legacy mode back to the main branch. If you want to use th…
I just added a beta branch for people who have already purchased Jimmy and the Pulsating Mass. This beta is running Jimmy through a program called mkxp, which is hopefully going to improve performance and give a few quality of life improvements. My big hope he…
We're trying out a new format for our weekly list of new games on Steam you might have missed, with a separate entry for each week's collection. You can check out previous games we've highlighted here . As always, these are five of the smaller g…
Don’t be put off by the cute facade that Jimmy And The Pulsating Mass wears. While this dreamlike RPG feels like its primary inspirations are from the Earthbound and Undertale sphere of family-friendly (though occasionally dark) RPGs, it’s not long…
Hey, everyone! It's been a long wait, but Jimmy and the Pulsating Mass is officially released as of right now! This has been a 4+ year odyssey. I've been working on this mostly in a vacuum for that time, and I'm so excited to see it out there. I'm so proud of …
Jimmy and the Pulsating Mass is officially complete! Unfortunately, we still have to play the waiting game a bit longer as I wait for Valve's internal review process and as I send out review copies. However, we don't have to wait for long! As of making this po…
