I love this so much and I'm distraught, I've played this game on both desktop and download; everytime it always stops at "Finale - Part 1" right after the "round rat short fella" says "But, first you must pay your rent". I desperately hope there's a solution as this is my favourite piece of art.
Hi Rougarou2!
For the browser version, try cleaning your browser history and offline website data (make sure your save files are completely wiped) and start from the last chapter. Keep your save files to a maximum of 3-4, and make sure you are close to your wireless source.
For the download version, some scenes may load slower than usual so you may need to wait a little bit more. (Also make sure your text speed isn't set to instant.) If all else fails, try skipping past that part holding ctrl in the download version. =) Hope this helps!
