A few updates have been uploaded recently to fix most of the issues found.

Some of the most significant improvements:

• Added a new section to the NPCs tutorial to teach knocking
• Added more sound visualization effects (for door impacts and knocking)
  • This should make it clearer when a door is accidentally hit while moving around
• Improved character physics, especially corner impact handling (should remove some ugly jittering)
• Added a visualizing triangle in the preview map making the starting position easier to find
• Improved the visibility of the knock icon
• Fixed an issue with the tool shooting light rays through walls while holding a door
  • My apologies to the speedrunner who found it, the issue was too serious to leave it in
