Wow, you have me blushing ;-) Your words are quite flattering. I am so glad to have created something that you connected with so deeply. Fingers crossed that I can get funding to build the Glum Buster full modern remake I dream of creating!
The video game I made for my sister is called "Puppy Stew". I did eventually release it to the public (on my sister's demand :-D ) via Newgrounds. It was a pretty big hit there (a couple Game of the Month accolades). Upon checking, it looks like it is available on some web game archives: e.g. https://kbhgames.com/game/puppy-stew
