This is a minor problem and may not be considered a problem at all, but I think it is better to just report it.
- Press and hold W to move
- Without letting go of W press ESC to get to the kismet screen
- Press ESC again to leave the kismet screen
- Actual Result: You are no longer moving.
- Expected result: You should continue moving forward
This could be intentional but I consider it a minor bug.
Respectfully other games I have played will let you keep running after pressing ESC the second time.
