I like the art-style and general take of the game, reminding me of some old Sierra point-and-click games.
Since you're asking for feedback to take this forward:
- Moving the character around in the world seems a bit pointless since it's only to switch scenes and talk to characters. I'd prefer to be able to just click, especially because the movement is slow and I get stuck in geometry.
- None of the dialogue options seemed to have any effect. I know this is meant as a demo but it might give players a better idea of your vision to have fewer options that actually mean something in terms of effects in the world and taking out characters and choices that aren't implemented.
