This is a basic platforming engine that I created from scratch (pun not intended, it means I did not use any tutorials for it). It includes spikes, falling spikes, falling spikes that stay in the ground, saws, moving saws, swinging saws, trampolines, 2 types of enemies, and coins. Also anti-stuck ducking
notice how the box is the same as the one in my profile... lvl 13 is so ez lol
