Thank you for the thoughtful comments and help with the bugs :) !
Initially I've planned the scoring system to be in according to the ingredients used, for example actual coffee recipes give good points but weird combinations could either give you bad points or some secret recipe could give the player the most points. The time based scoring sounds really good as well, combining both would make it more competitive for sure!
Thanks for telling about the bugs, I thought I had taken care of the door transition but apparently not :P
I'm really a newbie with making games and coding, so the variables used in Bitsy's dialog system are a bit of a head-scratcher still. I'll have to look into it more to get the inventory system to actually work as intended. Thank you for the input!
