NECRO!!!!
I bought this during the Steam sale when it was $2 and only played it now and man, I love it. Well... I loved the ending! The middle was very meh and draggy but it's probably because I played it in one sitting. Anyway, I saw quite a lot of people complaining about how difficult it is and really... man... you think this is difficult? Some people need to get their hands on Contra. Anyway, I did have some minor problems with the puzzles but I never actually got stuck at any of them.
But it's a great game. Will not be wasting my time trying to get the 8 stars (the fact that it takes 2 hours of doing nothing waiting for a cloud to move to get one of them is a testament to that) but I thoroughly enjoyed it. I love the story in all its weirdness, especially when all the games I've played recently have stories like this:
1. Take gun, shoot, kill, oh mai god hero lol.
2. You are woken up by (mother / childhood friend / love) for (festival / birthday / coming-of-age) ... save the world.
And to the OP, if you still need help... though you probably don't, you solve that puzzle by:
1. flip switch to get platforms to move.
2. jump of platform that moves vertically and drop ring.
3. flip the switch again, then again when the platforms are back in their original positions.
4. you should have one platform on the other side.
5. pick up the ring, climb up and flip the switch to release the ladder.
6. run over and climb that ladder, then stand on the platform with the glowy parts so you aren't affected by time.
7. drop the ring, then reverse time until the ladder is almost all the way back up (but not completely).
8. jump and climb the ladder as it falls.
