Checked it out, here are my thoughts:
Theme:
The game nails the theme less is more. Minimal story, but impact, simple basic platformer but pays off by being very polished. Even the game page was very minimal. Less was more for you through and through.
Visuals:
The game had stunning visuals. No surprise there. Staying simple with your overall game, seemed to allow you to get the game to extreme level of polish. The particle effects were fantastic. The animations seemed to being procedurally generated which looked phenomenal. The single enemy type was creepy and intimidating, but very well balanced. A simple color palette was utilized which made everything one giant cohesive experience.
Innovation:
This is the only area that I had to dock points. Since it is just another platformer, but by no means does that make this bad at all or generic. It is a platformer, but a fantastically polished platformer, especially for only a week of work.
Sounds/Music:
The game utilized sound and music almost to perfection here. It didn't drone music the entire, which allowed when the moments the music play be much more impactful. Level design and sound design really is what drove the story of the game and it did it very well.
Overall:
So I think it has been made pretty obvious that this game falls into the excellent and top tier games that were entered into the game jam just by all the chatter in the discord and word of mouth. But just hearing about it does not do it justice. This is a much worthwhile game to experience. The visuals are gorgeous, the controls are beyond responsive and have the right weight to them. The world builds and tells a story of going through a gloomy cave and eventually climbing out into the bright world. Eventually reaching and peaking a new height! Visually stunning and fun to play and gives off the feeling of journey, and a slight dark tone story telling reminiscent of shadow of the colossus. . Great work!
