That is a great idea for the game, I barely saw a game playing with the idea of scaling your view area for now. And this is something promising, please keep expanding (wink wink) the game further!
My single grievance is how the wall jump works. Mayhaps I'm too slow for this gig, but I failed again and again to progress due to (what I think is) very short timings for the jumps and direction switch. Have some pity towards not-so-hardcore platformer players :)
