This is one of the more inventive games with the theme of this jam! Rewinding in a literal manner by pushing the clock! Lots to love about this game:
1) The cryptic tutorial really adds to the ambience, as a puzzle game it's imperative that the player knows all of their tools down to the nitty gritty to exploit it to solve puzzles. Your game takes it a step further by making the learning process a puzzle on its own! Very difficult, but intriguing and quite fun.
2) Very great art, and ambience. Admittedly graphics are an integral to having people play your game and you have done well in that regard!
3) Very challenging puzzles indeed! This is something worth noting especially when making puzzles game - you may as well push people to point of roasting brains.
A few pointers of note:
1) There are a lot of waiting in this game - perhaps its more subjective to me, but my approach to puzzle games are of trial-and-error, via retrying failed mistakes often. And when I have to wait for the clock to accelerate faster (when I can't reach the hand and push it) - it's a bit painful to say the least. If we could manually accelerate the clock rate at any time, that would help the gameplay!
2) Collision glitches - when you're squeezed between the clock hand and obstacles, you may bounce out or bounce into or bounce pass the hand. Admittedly, I have used those same glitches to finish some hard levels (difficulty is always a plus in puzzle games by the way, good job). Collisions are always a pain to work with and it's problems can be evident here too. Don't let that detract too much - it's a good game generally!
This is enjoyable I would say. In layman's terms, this is a perfect representation of a 7/10. Like good fun, might not finish but good fun. I finished the game and it's enjoyable to say the least!
