Aw, thank you so much! The shadow/UFO turned out surprisingly nice, considering all it does is patrol randomly between all the points of interest (e.g. all the collectables), and then whenever you pick one up it's given your location as if it spotted you. If it's far away, it gets closer, if it's close, it suddenly gets very close :D I wonder if I should've made it a little faster still, just to absolutely force you to run...
What I didn't have enough time for was the story, which is a little unfortunate. Like, I had a whole system of picking options (there's only one currently, the very first 'who are you?'), but I didn't have time to write anything! Ah well. So it goes.
