I’m glad >:)
I’m also glad that I can disguise any bug as a feature hehehe.
On that bug you encountered: I didn’t get to test the web version when I uploaded it, but if you hit escape twice, it brings up the pause menu where you can press the resume button for the mouse cursor to disappear and work properly.
When testing it post-submission, it looks like the first esc press isn’t detected by the game running, which causes that issue.
