Playing through this game was amazing. At the start I kept wondering why I had so much choices in what to do, "Eat this stone or not?" But, playing further and reading over the description really brought all the pieces together.
I love the sounds you used. The damage sound fit in so nicely with the background music, as if the pianist just slams the keys down to a abrupt end. I actually ran into spikes a few times to make sure it wasn't just the background music!
I only got one play through in before this review, and got ending 1/3. I'm going to go back when I get time and see if I can see the rest of the dialogue. I felt the dialogue was very on point for the idea you were doing. Like all of Mary's thoughts were what made up all the dialogue, the sense of foreboding , and straight to the point.
I like how you did the chatter sound, and the constant static movement of Mary and any objects she comes across. It gives it that look of something isn't right, but it fits right in at the same time. And it moves great with the chatter sound!
My only suggestion would be a pause menu, but since the game is short it's not a big suggestion or must-have.
Well done! I look forward to seeing what the other dialogue is!
