The main deadlock here is extremely subtle, and finding a way to avoid it subtler yet. Spent ages working in the editor before managing to rule out what was impossible, and then finally out of the ashes a solution emerged.
The flavor of this level is pain. It looks like a demonic blob of intricacy and chaos. In this case, the chaos mostly functions as obfuscation and intimidation. I spent a long time in the editor replacing blocks with walls, and after doing so had a fairly nice time reaching the exit. DM me on discord and I'll send you the level code for the cleaned version of this level in my drafts.
