Make sure to consider the filesize of a gamejam game. I'm typing this up while waiting for the install and unzip, because this is the biggest file so far in the jam I've seen.
After booting it up I realise that it's likely these fancy assets that made the game so big, but I don't know if they are adding much to be honest. Having a more simple artstyle would have made the different assets you have clash a lot less with each other.
Also, a crosshair would have been really nice. Especially since I originally thought I couldn't pick up the key, but that was only because I clicked on the pillar instead...
