A downloadable game for Windows, macOS, and Linux

A short combat demo for our yet-to-be-named story based boss rush game where you fight a mysterious black bird. What could be the reason for the confrontation?

This is still very much a work in progress, so any feedback would be really appreciated! Let us know in the comments section or join our Discord and be a bigger part of the development. You can also follow us on Twitter to stay updated~

Play with keyboard or with console controllers (only tested with PS4 and Xbox controllers but it should work with anything else, let us know if it doesn't!) And re-bind buttons to your heart's content (keyboard movement is locked to WASD for now but we'll implement arrow keys movement soon)
