(INSTRUCTIONS CURRENTLY BROKEN!!!)
What you're going to need to do is tell Chrome that Flash can use this page.
Normally it does it by itself, but this site seems to be a bit derpy.
You need to go into the plugins page and find the flash player. You should see a blocked page section and an allowed page section.
Just click "add" next to the "allow" section and slip the URL into the box.
If for some reason you don't know what the URL is, here ya go! https://nomnomnami.itch.io/dress-treat
You may have to download an extension that allows you to get to the plugins page, but you should be able to reach The flash settings through the settings panel too! Just type flash into the search bar at the top of the settings page and the yellow text box with the word "FLASH" should stick out like a sore thumb.
Press the option that it's linked to and the next page should have an option that is highlighted yellow. Click it and hey presto! Just slip the URL into the correct location.
And there you go! You can now play Dress Treat in the Chrome browser! No more fiddling with Internet explorer! HISS BITE HISS!
Have fun! =D
