This is a fairly small update in terms of actual features, and is mostly just an update to the underlying Unity engine to be on the latest version. Other small bug fixes and minor improvements are included.
v0.13.1 - Major change to "Bracing"
Things just got less frustrating. Previously, you could hold the Shift key to "Brace", which would make you resist forces (like Rift forces) and stay in one spot more easily. Not bracing usually meant getting pulled into a Rift, or flung all over the place. But I realized that A) New players didn't really understand this concept, and didn't use it enough, and got frustrated, and B) By the later levels, experienced players were just holding down the Shift key almost 100% of the time, which was more of a hassle than a skill.
So, with this update, Bracing is now automatic. Any time you're not actively walking in a direction, you'll automatically brace. This makes everything feel much more in control than it did before.
For speedrunners, who appreciated the ability not to brace in cases where it helped them go faster, you can still have that experience, by making sure you're always holding down on a movement key if you want to bypass the Auto-Brace behavior.
v0.13.0 - Three new levels, and major changes to the Demo
The big feature in 0.13 is the addition of three new levels towards the start of the game. Look for "Tunnel Vision", "Run the Gauntlet", and "Virtual Velocity" in the level selection list, near the top.
These new levels extend the initial "Orientation Course" portion of the game, and are now included in the Demo. The Demo used to be a single level, taking maybe 5-10 minutes on average. The Demo now contains 4 levels, and is probably more like a 20-30 minute experience.
v0.12.2 - More cutscene/story content
This release brings the story up to the end of the Advanced Training section of the game, which means about half of the existing levels now have their story content.
0.12.1-f2 - Bug fix for Research Labs levels
This is a minor bug fix release, which corrects a serious bug occurring in levels like "Red Shift".
v0.12.1 - 8 new "Hard Mode" levels
8 more levels have had Hard Mode versions added. Look for them under the Challenge Modes menu.
v0.12.0 - New story dialogues, one new level, and 6 new 'Hard Mode' levels.
The main Story now runs up through the level 'Full Swing'. One brand-new level has been added to the 'Advanced Training' section, named 'Logic Gates'. And 6 levels have been upgraded with a 'Hard Mode' version.
v0.11 - Introducing "Hard Mode"
This update isn't for everyone... It introduces the start of a new layer of the game, where existing levels have had the difficulty ramped up to 11. Have fun revisiting familiar levels that now contain new and extreme challenges.
I'm eventually planning on unlocking "Hard Mode" as a kind of "New Game+" feature, after you finish the game under its standard difficulty. But for now, in order to make it easier to get feedback from players, you'll find a new tab in the "Challenge Modes" screen. Give them a try, and don't be shy with the feedback.
For now, 9 levels have been upgraded with "Hard Mode", just the levels of the Basic Assessment course. The rest of the levels will follow, most likely pairing up with adding the remaining cutscenes/story to the levels.
v0.10.0 - Major update with the start of the Story
Character dialogue (with professional voice acting) has been added to the first 12 levels or so, with more to come in future updates. Each new major update will continue the story.
This release also includes a ton of other smaller changes, new secrets, major performance improvements.
Gravia now has about 65 levels, over 80 secrets to be found, with more to come.
v0.9.3: Three new levels: 'Heat Sink', 'Firepower' and 'Stop, Drop & Roll'
This release adds three more levels in the Reactor Core area, with a new "fire tunnel" mechanic.
