A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

- Fixed the speedrun achievement being attainable just by watching the credits from the main menu (whoops) - Fixed a bossfight incorrectly granting you a powerup if you didn't have it yet - Hopefully fixed a rare issue with controls in the credit screen - Added a version number in the main menu
Hi everyone! As I mentioned earlier this year, we have been working on a new version of the game with the intent of fixing various problems that have plagued the game for years now, including the game just straight up not functioning on Macs anymore. The list of changes/additions includes: - Steam Achievements - Mac/Linux support - Steam Deck support (not reflected yet on the store page, we're going through the verification) - Proper gamepad support, also on Mac/Linux - Bugfixes - 60 FPS - Steam Overlay (the Overlay was previously disabled because it caused rendering issues) Apologies for the
As the title says, the full OST should now be available once more. Apologies for the trouble.
The soundtrack for Environmental Station Alpha has been nonfunctional for some time now without me realizing. The reason for this was that the OST was implemented back before Steam had a dedicated soundtrack feature; during those days the way to add an OST on Steam was to release it as DLC. When I converted the soundtrack DLC into a Steam soundtrack, I assumed that the actual audio files would stay around, but this actually wasn't the case and the conversion just wiped them entirely. I really should've noticed this; my apologies. It seems that the lossless FLAC files for the audio are currentl
ESA has currently some issues with crashing on Win11 platforms, and as announced previously, the MacOS version doesn't run at all. We're working on addressing these issues by porting the game to a new codebase which makes handling of these things easier and/or actually possible. At the same time the gamepad support should become better, as a nice bonus. In the meantime it's recommended that you hold off from purchasing the game because the porting will take a bit of time and while it's underway the issues will be around. Apologies for the trouble; I had hoped to get these things handled togeth
The game has stopped working on newer versions of MacOS due to technical reasons that I can't fix right now. For that reason, I've disabled MacOS support for the time being. I'm intending for this to be temporary, but fixing the issue will require quite substantial work and I'm not sure what the timeline for that will be. Huge apologies for the issues people have had with the game; I'm hoping that a bunch of them can be addressed in a future update. Especially this MacOS issue and the wonky controller support are on my mind. Apologies also for not reacting to these issues sooner.
The green switch block bug should now be gone. Alongside that I managed to figure out a semi-fix for the yellow teleporter alt+tab issue, as well as fix some small issues related to the game timer. So yeah. I had known about the switch bug for some time, but had assumed it to be a rare problem due to me not having touched that bit of the code since release. I filed it away as a "fix this in a future bugfix patch", but only now noticed how common it was. It's embarrassing that just by looking at the Steam forums more often I would've noticed the seriousness of the bug, and I deeply apologize fo
Noita, a game I've been working on in the Nolla Games team, will be coming to Steam Early Access on September 24th and has a new trailer! Check out the trailer here: https://www.youtube.com/watch?v=smkdscv6SJs Noita's Steam page (if you're interested, do give it a wishlist): https://store.steampowered.com/app/881100/Noita/ The game is an action roguelite with the twist of every pixel in the game world being physically simulated. What this means is that the world is made of different materials that can be destroyed and react to each other. Wood burns, and water coming into contact with fire cre
- Fixed the previously implemented system to make entering one-tile-high passages take all wall types into account to remove inconsistencies.
- Fixed the new option in the settings menu overlapping other options - Fixed a bug in the new feature for entering tight passages more easily - Made Serpent 5 turn slower in the first phase
Phew! I've been really busy with business and Baba Is You, but took some time today to implement some much-needed updates: - Made it easier to get into one-tile-high passages - Added the ability to turn the water/fire wavey effect on/off to the settings (the "Shaders on/off" option) - Fixed boss healthbar going behind objects - Fixed lava in the Multicore fight bugging out - Hopefully fixed being able to skip credits sequences too early - Made Overgrowth's third phase do less damage with its tentacles (I should spend some more time adjusting this and some other bosses) - Added a lua hook for t
Some players have had an issue where the game doesn't render areas correctly when in an underwater/high-temperature area. I'm planning to release a larger bugfix patch later on, but right now don't have the resources to do so, so as a placeholder fix the special rendering effects in said areas have been disabled for the time being. Apologies for the inconvenience.
Environmental Station Alpha has got an update with optimizations to the gameplay itself. There was some old code that was unnecessarily memory-heavy, and replacing that resulted in the FPS increasing to about 3 times what it used to be. The FPS is still locked, but on computers that used to experience slowdown, that should be much, much rarer now!
Another small update! Previously, if you set the sound volume too low, some sounds might not play at all; this has now been fixed.
Environmental Station Alpha has updated! The big new thing is that the level-loading code is much more optimized now, leading to faster loading times especially on older computers! The new version also removes some rng elements, and you can now skip the credits sequence if you've already seen it. There was also a small graphical glitch related to the new water effect that is now fixed. NOTE! The new optimizations have altered the codebase in a significant way, so it's possible that there are new bugs in the game. If you enter a room and see somethingout of place (for example that there's an en
