Ok, after 1 hour of trying, I get all endings! (Don't post screenshot for Spoiler reasons, the ASMR makes me LOL)
Agreed with the comment of the 4 seconds delay the Rewind button has. It's annoying when trying to do all the endings. But the rest was a nice experience. Congratulations!
Please if you can, check Rewind Madness, my game. Thank you
