It was interesting!
The bounciness mechanic kinda reminds me of this video I saw

I think for controller it would work pretty well.
But on keyboard lvl 5 (angled spiked corridor) was particularly frustrating.
Since it's sometimes difficult to perfectly hit two keys at the same time to start.
The 'usual' way of compensating for this accuracy issue in keyboard, is to use the computer's "accuracy" tool - the mouse.
But I'm not sure if that's the right call here
Anyway - cool idea :). Hope it does well
