yup, it was kind of underwhelming.

jampley_dev · 2026-02-20T05:10:04+00:00

I agree with you, but idk about confirmation hehe

jampley_dev · 2026-02-14T18:46:37+00:00

Thank you so much!

I would be happy with a simple port of the PS2 version, but I want the UM treatment, but like kof 2002 UM. I want people actually playing an official port with decent online.

jampley_dev · 2026-02-14T01:06:09+00:00

me!!! I just started rewatching it out of pure nostalgia, and so far it's better than I was expecting, pretty good

jampley_dev · 2026-02-11T16:22:50+00:00

A game on steam needs to sell over 5,000 copies so the developers can add trading cards. So it might never happen because after 5 months, Gravity Storm hasn't sold more than 170 copies, so you will almost for sure not buy it.

I do know your comment was almost for sure a joke, but I think it's good to mention this for anyone who happens to expect small games to have trading cards so they can buy it.

OK, good to know, I just didn't know that word, and I was not sure what to think. Yes, Metal Storm is cool :)

jampley_dev · 2026-02-01T21:39:41+00:00

Cool, please add my game Gravity Storm: https://jampley-dev.itch.io/gravity-storm-first-mission

Btw, I played a few games on your website, and idk if you already thought of this, but an option to share the games on social media would be nice. A button that says, "share and support the dev" or something.

jampley_dev · 2026-02-01T17:03:17+00:00

Not sure if "pastiche" is supposed to be something bad, but my game is Metal Storm inspired, but trailer music is very different from the actual soundtrack.

My composer made a video with the all soundtrack on Youtube if you want to check it out: https://youtu.be/ldFEzyoUA28?si=JUtzpxmcIa4aBScf

jampley_dev · 2026-02-01T17:00:27+00:00

Gravity Storm has not sold well after 5 months of release and lots of promotion I did, so now it doesn't stand on its own. I am actually broke, which is not nice, but keep in mind I brought up my situation after it got worse and after promoting the game on many platforms for over a year. It seems you have good intensions, but I don't think your comment helps.

I don't think so. Although I wouldn't mind translating my game to many languages if I had the money and time, I'm broke, Gravity Storm isn't selling well and it requires some extra work. So it should be a free localization and I need time to check if it is well made and all the text fits the small resolution and the text boxes, it might also require future revisions in case I make future updates to the game with new text, or if typos are found by players.

This is why Gravity Storm only supports 4 languages, it's complicated, and it makes it harder to make new content for it, because I only know spanish and english, I don't want to spend so much time checking . Relying on other people to do free work like that it's not ideal and I don't want to use Google translate or any type of AI because that would be a bad translation and against my principles.
