Love the atmosphere, and the low-poly and low-res aesthetic. It all works to set a really ominous, mysterious feeling when playing.
Don't want to spoil it in the comments, but the realisation of what's expected on the final day is a great moment :)
I'd have loved some more audio - the sounds that play when going to the next day were fantastic, but would be great to have some ambient bg noise, sounds when things are dropped etc.
