Break the laws of physics, dash and shoot your way through levels full of hazards and machines gone rogue. In this retro game, you control Project Gravity Storm, an advanced machine able to control gravity itself; however, the mother computer will not make things easy for you.

Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Jul 30 → 0.14/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Indie game with incredibly smooth control; Even in the more challenging rooms it's feels great, with a lot of different mechanics you can use to your advantage. I really enjoyed playing the game, I'll be revisiting it to get some more achievements done. I love that even though it's short, it has replayability value. Highly recommended; I really hope to see more games from the dev. :D
Un juego bastante divertido con controles muy fluios, buenas mecánicas, su buen toque de dificultad y un pixelart muy bonito. Espero que este desarrollador siga sacando más juegos :D

A fantastic game with incredible level design and interesting enemies! The game remind me of a lot of past games i have played since I was a kid and I loved it all the way through it is quite challenge at times but that where the fun begins! All in short i Highly recommend getting this game you'll enjoy the games for what it is!
I had a lot of fun with this game. I'm a huge retro gaming fan, and this brought me back to the likes of Metal Storm for NES. The animations were cute, and the music was great. The gravity switching mechanic (and overall controls) worked great, and added some extra challenge to getting through certain paths throughout the game. Kudos to Jampley Games for this one! I definitely recommend giving this game a try, especially if you're into that retro platforming vibe.
Fun game, works well on Steam Deck - reminds me a lot of a mix of Warp Tank from UFO 50 and Megaman. Some of the bosses are hard!
finally got to play the release of this game! Its a fun little platformer with good combat and a nostalgic feel. The art and music are good, and it definitley brings back some of that retro difficulty. I could see it being an interesting game to speed run!
Es un juego muy bien hecho, muy bien pensado, a mí me gustó muchísimo. Tiene toda la inspiración retro pero con identidad propia. Las mecánicas me encantaron, es un juego que te hace pensar y atreverte a avanzar saliéndose de los patrones conocidos de los juegos de plataformas convencionales.
This was a short and sweet game reminiscent of Metal Storm. The sprite work, level design, and soundtrack all shine, and it doesn't overstay its welcome. It's also tough but fair, and avoids ever getting rage inducing like retro-inspired indies tend to be sometimes. Definitely worth checking out.
Sublime. 10/10, muchas referencias de robots.
Graceful and nuanced. I would recommend playing it to see if you got the retro gaming chops that it tests. It's hard enough to keep you hooked.
