Tokyo Heist: What is going on.

I've decided after much thought to base this game around a core parkour concept. Basically, your only adversary now, is spikes (other ground objects like this) , and falls. No enemies and turrets. I'd like to make this game incredibly fast paced parkouring, with lots of long jumps, and wall jumps, and tons of exploring, more than level based. Check out these images, i've decided to make it pixelly too.
