Remarkable: I think it's interesting that the game uses such a varied layout. There are many different obstacles of different shapes and sizes, and I think that's neat.
Needs Improvement: Almost immediately I found a major bug that completely breaks the game. If you use WASD instead of the arrow keys, the camera gets really wacky and shoots off the stage. I'm not sure what causes this, but I was able to reproduce it multiple times, and it effectively softlocks the game. Additionally, the way the level resets is overly punishing and very jarring. For starters, there are no checkpoints, so it feels really bad if you happen to lose close to the end, only to get sent back to the beginning. There is also no actual "level reset", as the ball's position is simply moved back to the start. This means that all of the obstacles you broke are still gone, which removes any element of overcoming the difficulty of a particularly challenging obstacle. Theoretically speaking, you could simply brute force your way through the game, clearing a trail of obstacles only to respawn and do it again.
Successful: I think the overall concept of the game is pretty solid. While it lacks polish, the fundamental idea of falling through different levels and dodging moving platforms is really fun. Reaction based games are something I really enjoy, and I even challenged myself to get through an entire section without hitting a single block. This was the main reason I disliked the lack of checkpoints and hard resets, as it meant I had to restart the game whenever I wanted to try this again. That said, the core gameplay loop is fun, which is ultimately the most important thing.
General: Overall, I feel this is a solid foundation for a game, but it is in desperate need of further tweaks to make it feel more fluid. One other thing I wanted to note is that your unity project seems really disorganized, with materials, prefabs, and scripts strewn about in one place. I highly recommend creating specific folders (Prefabs, Scripts, etc) to help organize the different elements of your game. As your game increases in size it will become far more difficult to navigate a maze of different elements to find the one that you want.
