Thank you for the kind words! Happy you enjoyed it!
I would NOT DARE to pull a jump scare in a game like this... That would just be rude, haha XD
It being very dark was intentional. The intent from a design perspective was to deliver a dynamic feeling meta-ending (referencing the jam) using a simple mechanic. Going from the deep dark, to the cheerful bright. Like a roller coaster of sorts. Very observant of you to notice!
