I can't take all the credit, it was my girlfriend (strailks) and I who made it. She's the one who wrote the music herself, and wrote about half the code. Glad you enjoyed the game!

Thanks for the info, I don't own a Mac, but I use Unity's Mac build, so I can't test it, but I try to upload it. I think I know what I did wrong and will fix it for next time. We're glad you enjoyed the game, and the idea for the rewind is that it moves you back 2 seconds no matter what, so we wanted it to sometimes be just a time waster, and end up dropping you without a block to stand on.

Yeah, we know about that. We wanted the game to be difficult, so that would be part of the challenge. When testing I got annoyed that I would keep getting hit (I'm not great at the game, and we had some levels that were way harder at stages during testing) so a trick I realized is to not try to blitz through it, and wait for a few seconds on a safe block, then keep going. That way you would have something safe to fall back on.  The story was a fun part of creating the game for us, and we got to include a lot of humor in it.

I'm not sure how you got the rewind clock to not disappear, that one is a new one. For the falling to your doom, the idea was to always go back in time 2 seconds, so it wasn't always safe. It encourages the player to take their time, which makes the level itself more difficult because of the disappearing blocks.
