Fair! Yeah I haven't checked all the pickups, but the ones at the bottom of the bullet hell pit right before the boss, I was able to farm those two by picking them up and then dying, respawning at the save room right above them, and they would be there again.
One more nitpick I would want to add, the font is a bit hard on the eyes in large paragraphs, the intro text scrawl was not the most pleasant to read.
