We have released the controller support & engine updates advertised last year on the main branch! As previously discussed, this adds support for controllers in line with the support added to our recent Xbox release. It also updates the game to the latest version of Visionaire, which has been shown to resolve some CTDs that people were experiencing before.
In addition to those core changes, it also addresses a few minor art issues and smooths certain puzzle solutions. Nothing major.
If you experience any new crashes with this build, please let us know. The "legacy" branch can be activated in the Steam beta branch settings at any time to switch back to the pre-update code.
