Good news! All of my games have been fixed.

The final damage report due to the Google Chrome update is:

• 20 games were affected and blank screened: 20 games needed to be reuploaded.
• 17 of these games were on multiple websites: Newgrounds, Itch.io, and GameJolt.
• In total, I needed to reupload 45 files across those three sites.
• This whole process took about a full day. 

Although the solution was a bit tedious, I'm just happy that everything has returned to normal! Plus, one day isn't too big of a sacrifice in the long run.

Cheers!
