We've got a brand new build available and will be making incremental updates now to the deck-test branch in the versions and betas. The latest version brings the following.
Online Co-Op Is available throughout the campaign. This is in testing and needs your feedback!
Squadron Survivors mode added. It's a take on the Vampire Survivors formula. The mode is incomplete currently.
Several tweaks to controls (a new Mouse and Keyboard Option)
Shaders have been rewritten.
Full support for Windows, Linux and Steamdeck.
As always please provide feedback in the community forums. We'd love to know how it's going for you.
