Generation Retro Fix by LNLenost, 100% Complete

Today, I tried playing the level Generation Retro Fix by LNLenost. This level was inspired by a video from GDColon, and I'll include the link below. This is a remix version of the level Generation Retro by Aarathodiiez (the final level in the Poison Gauntlet). I found it quite interesting. Although it is an unrated level, I think its difficulty might be around Harder.
