At first, the Nihil zone feels truly impossible, but once you try over and over you finally get the hang of it and beat it like a boss. Great game, great music, and something a sequel or level editor for is required!
Somehow managed to cheese "Hard - Source Fight" doing Bottom-Left and Bottom-Right gems first, then staying on an above platform to shoot Top-Right. When I was fighting the Source (rainbow man) I glitched through the one-ways at the door to enter the boss room and shot him through there, as projectiles cannot go through the wrong way of a one-way.
i find the Omega Catalog the most expensive yet best bonus shop item IN THE GAME. once i got full Omega stuff and i, at that point, flew OVER the Wall and got a medal for "nuking" the emperor Dodo, who called penguins fat AND dumb for not being able to fly and that they still call themselves "birds", saying it in full typos (e.g. your is ur.) He deserved it
