I will try to compile a new version using the older libraries soon :/
I guees that the newer libraries could be using WebGL 2.0 instead WebGL and that make the software less compatible than before.
I tried Spritestack in a friend's pc and it opened fine and the difference between his PC and mine was that when we go to chrome://gpu i have the WebGL 2.0 functions unsupported and while my friend's one does have supported it.
This is just an hypothesis but i mention it just in case.
Update: this morning i got this

A half of the elements are visible and react to my clics. There's still no canvas, buffer, and top bar and their respective functions.
It is impossible to draw but it's a great progress .
Assuming it's an update that only works through the app, and not one you can just download from itch.io (which says it was last updated 3 days ago) then no, because the old, working version I have won't (or can't?) auto-update, and the new version is still broken.
Also, I thought to try the browser version in Chrome, instead of Firefox which I had been using, and it turns out it only partially loads (same as what Waltz 89 got) when using the browser version in Chrome.
