This is a very good demo, and I enjoyed it a lot. Tommy and Ellis are both especially adorable, but it does make me wonder: would it be possible to get into a poly relationship with them both in the full game? Because their relationship already feels like it's the start of a romance, and I don't want to have to betray one to get the other...
On a different note, the demo file was very large for a game its size, and I note that you've got a very large number of sprites that are either duplicates or variants that I don't think are ever used in the game. It would probably make sense to only include the necessary sprites in the distribution package to reduce its size.
Anyway, I hope this goes well. Good luck with the game!
