Thank you for the feedback.
Please keep in mind that as of now, CHORDOSIS is not out on Steam, and it doesn't have a dedicated installer.
Please be careful, make sure your version of the game is legit, and not a scam.
The itch.io version here is the only legit version for now.
I'm not sure why mouse-clicks only register in the UI. If you have a gamepad, please try to disconnect it, and try to click outside the game and back in.
Make sure nothing is "stealing" your mouse input. OBS or Streamlabs likes to do that.
Also, the van's door only gets intractable when you pick-up the in-game controller from the bed. You can open the door by holding the left mouse button and dragging the mouse.
Thank you,
Adam
