This game has a really good premise, but it is definitely unfinished. I really like the pre-rendered 3D art; it's very cute! Although, the text at the start is quite small, and the font is hard to read. I like that pun: "the off and on again."
I hope you'll pardon the "intrusion" but I opened up the browser's network inspector to check what exactly was taking so long to download. The sprites for the main character are 600 x 600 ??
Even zooming my browser in all the way (and I mean all the way) only brings the character up to about 150 x 150, so you're not even retaining the fidelity of the original renders.
If you shrunk down the images closer to their actual display size using your preferred algorithm of choice (this example uses fant) you can reduce the file size exponentially!
Other than that, good work!
