Pretty nice demo! All that i can say in cons is:
1. TOO dark in "scary moments", i can barely see anything for no reason.
2. Unskipable dialogues after death.
3. Said to econome sprint, but in dangerous i couldn't use it. (as i think it's only demo issue of lack of playable places)
Оthеrwisе it can be a very atmospheric, melancholic game about attempts to protect your sister!
