Amazing idea for a mechanic, you can and definitely did end up doing a lot of really cool things with it!
I thought the movement was a bit slippery though, and not super fun to engage with. The camera also couldn't always keep up with my player when I went super fast, I think because you had unlimited acceleration?
The blowing up of blocks was also a bit random, especially on the 3x3 red block bit where I kinda just had to sit there for 30 seconds until enough blocks cleared for me to get through.
The visuals were very well done, especially with all the camera effects that you added! Particles are Unity standard but you made good use of them, even if the round blobs don't fit particularly well with the more square environment you got going on.
