Haha, I see you got some inspiration from a certain famous visual novel. I don't want to spoil anything, but it was a pleasant surprise to suddenly see more depth than the game lets on. I'm not sure if I experienced everything, but very nice work!
It actually reminded me of another, lesser-known visual novel that I bet you'd enjoy and could get some inspiration from, dev (assuming you don't know it already). It's called "Save the Date" by Paper Dino. Much like yours, there's more going on under the surface than it initially lets on, and the more you push, the more it will surprise you.
One final word of advice: Ren'Py supports exporting to HTML5 for running your visual novel as a browser game instead of a download, which will make people much more likely to play it in a game jam. Something you may wish to consider next time.
But I enjoyed it! Keep it up!!
