Hmm, i'll try. So at the start i was going to the corner, where blue crystal is on a rock, i tryed jump to it couple times and then goes to the yellow crystal in the spikes. I returned it to the center and then i tryed to pick up red staff, that floating near the center and i just goes through it. At first i though that i can't pick it up by the purpose, but it looked so pickupable :D so after i died at the trap and restarted the game items started to pick up. So i can't really provide more specific, may be it was button mashing stuff that glitched the game, i don't know
