Camera and movement - yeah, that's the whole world with different tricks and stuff to make it feels better. Coyoute jump, spring arm, camera collision, air control, climb on slight. When it's done right no one will notice. But when you've made even slight mistake - players will feel it :)
Lightning is a little bit off but thats may be an art choice which I didn't understand.
Overall I liked the game!
It's simple, nice camera intro (not many games playing with camera) and smooth animations!
Simple shapes and textures play nice with each other!
Good job!
