Thanks for your comments :)
I particularly like your idea at the end about how the senses could interact; and this would definitely have been a more complete way to have taken the game for sure. It's got me thinking about how they could work better together, instead of just being more reflective of the human experience.
The other two are bugs I suppose... I think I didn't test collisions enough, just assuming it would work in 2D... haha. And yeah the dialogues definitely shouldn't have been skipping about, although I did have some click detection issues myself when playing which I didn't have time to resolve.
Glad you felt it was pretty complete otherwise :)
