chill game, I like the postal music, but a couple of suggestions!
first, if this is a flash game, you can emulate it with ruffle to avoid having people open NG player. Most people would probably wanna play something like this on the site itself instead of opening up the NG player on their computer. There's a little box you can tic when embedding the height and width. Should say "emulate with ruffle"
second, with the glasses being an accessory, it's a bit hard to click and drag. I would suggest making the movie clip have a completely transparent background so it's easier to move around and click on.
super simple, but I'm happy to see that old school flash is being kept alive :) good job for your first game
