One feedback incoming.
First of all the art style is astonishing. It's what made me want to try the game.
In terms of gameplay I'm just not a fan of runners, so it was slightly tiresome to play. But the level design is beautiful so that was helping to pass the time while running.
The story was nice. Even as short as the demo is it was captivating. The memories help the story to unfold in a good pace. I would probably play this game on release for the sake of the story.
Loved the UI. Minimalistic, intuitive, fits the game style.
Loved(!!) the music.
Further are some suggestions that I thought about while playing. It's not the comments about the demo, more what I would love to see in full release:
1) I hope in the full release you will include more different assets on the levels so are not reused multiple times. Mostly the cars and the big house.
2) Returning each time to train car I was hoping that the notes on the clickable things would give new information. They don't and now it's not a lot to do but reading the memory.
3) All the levels can be passed with just double jump, so no idea why do I need speeding up for. Hope in future you would add obstacles that are only passable by combining sprint and double jump
And tiny notes for the demo:
- When the little jackal puts on the headphones the music end abruptly. A fade out would sound better
- English translation needs a bit of editing
