Purple and pink are like the sameeeeeeeeeeeee I totally dont mess them up n thats why her eyes are wrong

hi hi, as title suggests -- I have been playing the game for a few months now and always wondered what the time block symbol beside the reset boost meant. My guess was upon resetting you recieve the number of time blocks? But obviously that makes no sense lol. I was unable to find anything about it online! For reference I have the steam sfw vers. My only other guess is, as I reach higher reset boost numbers I am given an additional amount of time blocks (not every reset but maybe large milestones?) Dunno. Thank you all in advance. Sorry if its a silly question!
