A brand new game
for Windows, Linux, Mac, HTML5, 3DS Homebrew and more
10th January, 2020
With any luck, you shouldn't be able to tell the difference, and everything will continue to work swimmingly.
I'm not sure what the exact rule for cache-update-checks is, especially if you're playing with an "Add to Home Screen" kind of bookmark, but it appears to be doing a decent job of keeping up to date.
Please do give it a try, and let me know how you get on with the update, reporting any oddities or (hopefully not!!) complete breakdowns along the way.
You can Play Shoebox here.
The updated version number on the main menu should be v1.128 or higher.
