hello and thanks! :D
and yes, they do! the choices you pick effects what parts of the story you see too. for example: your choice to talk or not talk to your fans. the conversation you have with them later in the greenroom will reflect on that. same goes for the amount of "good" or "bad" choices you make, or whether you play clyde's first mini game or not (this one decides who follows you around later in the full game...*hint**hint*)
I tried to make sure that the choices matter because I wanted to make a game that was replayable! I also originally only planned for 2-3 endings and that's mentioned at the end of the demo if you got a neutral end but with the way the writing is going...theres going to be a lot more haha.
