Very solidly made game. Great visual style - simple, clean models, enhanced with a few well placed particle and post-processing effects to sell the atmosphere. The lighting and geometry within the level design, along with the unexpected little tutorial give a real taste of something much bigger budget than a solo dev under Game Jam constraints.
A tragic little vignette with very polished production values. The only thing I'd really change is to add some more ambient audio to the starting scene, which seems to be silent, apart from the scrolling text.
Excellent work!
