You can try the new version if you switch the game's beta channel on Steam to "testing".
I'd be grateful to hear if you are able to play the game normally (from intro to outro).
Changes list:
1.13.0
- Added new puzzle right after getting the translocator to teach the behaviour of cardboards better; also changed the way a secret area works there; and added a new secret area here too
- Fixed possible bug when putting objects into color machine
- Improved handling of rank plates (can get pulled out of socket with beam; has better rotation while carrying)
- Changed the way 2 secret areas near the purple crystal work (require knowledge but not abilities from later in the game)
- Mini volcanos can now be used to set things on fire
- Improved button prompt hint when you first need to burn a cardboard
- Made progression visually clearer in Volcano1 because most people didn't know where to go
- Improved magnet behaviour when attracting things to you (so they don't wildly swirl around you anymore and you can now float up heavy objects while attracting light ones)
- If player gets stuck inside the door in Volcano4 they will now get teleported in front of the door and get an additional hint displayed
- Don't need to do the way back across the big water under the wood logs anymore, only need to get to the chest.
- Fixed laser trigger becoming green when the force beam goes through it (it now gets ignored)
- Fixed missing footstep sounds when strafing of walking backwards
- Shells now a little more visible
- Fixed bug with grave detector introduced in the last update
