Just beat it. Lovely game, very authentic faux PSX look, challenging but not too difficult.
I did kinda cheese it though. If you press the dodge button twice quickly the character model kinda skips forward without an animation, bypassing all collision. Useful for avoiding enemies, not so useful when you end up skipping past the wall while fighting death and falling into the void below. It's a good thing you had the foresight to add a death trigger below the level.
Overall, a really cool short game. I especially liked the parody of the PSX bootup logos.
