Sorry you didn't enjoy it too much, the feedback is appreciated.
Stepping off of any 'flipped' tile causes them to activate, I just wrote 'jump' in the tutorial because it was difficult to come up with a way to describe that which wasn't too wordy otherwise, will definitely be working on making any in-game explanations clearer and more in-depth in the future.
I think if I were to explore a similar mechanic again, I would remove the random element, though I do think them being randomized provides a very different type of challenge.
