I've encountered a couple of bugs and I just replayed the game to check if I can catch more this is what I got:
whenever you reset the game or enter a new game the sound effects will double and get out of sync (every sound effect will play twice or thrice depending on how many times the game reset
you can kinda just break the game by reloading the scenes at the beginning
reloading the scene doesn't restart the progress from the first phase of the game (before the dude was shot) to what it was at the beginning of the scene . I've actually noticed it makes just as much progress on the first phase as getting into a new area (you can create like that some weird situations where the man has been shot in a completely different location than he should have and you get the wrong cutscene)
I've also noticed that you can get the dialogue for when you shoot your old man while talking to him in the tent thingy although you didn't shot him (I don't remember how I did it I cant seem to be able to recreate that)
you can kinda like break the dialogues by clicking on the people
this one I'm not sure if its intentional but you can also skip the whole dialogue of that redstar by giving him his poster back
and last but not least I know this is intentional and that its just a chat code so you as a developer can better see how the game interacts, however! don't ask me how I know this but ctrl + windows reverses time
hope this helps
