I hope so, I think I just take a timeout. About any questions about incognitor and other - you can trust me, I'm JS Developer and know how to work with browsers. Only thing - I'm typing a little too fast and if there is a keyboard shortcut for "Clear code" than I could press it and didn't notice.
If you don’t mind, I would like to make an offer of autosave: save the game code in another localChange variable, not by Ctrl + s, but by timer. A kind of backup. From it, it would be possible to restore the last autosave.
P.S. Windows 10 x64 / Chrome 79.0.3945.130
UPD. And yes, I have a mid-development version saved.
UPD2. Oh, i remember one more case when I almost lost my game, but stopped immediately. Ctrl+A -> press any key =) It's very very stupid case, but it can be. I once worked with a very similar one. Script is checking for text changes and if the text size quickly decreased to 10% or less - it threw an error.
