Thank you! i'm glad you enjoyed it. i debated for a while about letting the player push or walk through the past selves - but kinda felt that the present not being able to affect the past, but the past interfereing with the present, felt better. or, worse? any, it felt right.
i've actually got a few extra levels mapped out in unity, and i'm hoping to add them once the jam unlocks updating (this is my first jam that did this... i kinda don't like it?). i hope you come back and try it again some time!
