That grind, day after day after day... even if you don't get the sense all that much time passes before he's caught in it. Maybe a bit longer a build?
When the darkness creeps up on the guy (the purple being - if that's his symbol or no) the animation felt a bit choppy, but when he wakes up in his... dreams (?) it's a whole other world! So smooth in comparison. The quality feels a bit inconsistent like that, but also like you get better as you go.
I can't say I really understand what happened though. I thought he was falling victim to something but... then he gets up and feels great? Who was that purple guy? Sickness? A dream eater...? And how does he overcome him?
I feel like it could be clearer, but otherwise it's not bad.
