Took me a few tries, but I was eventually able to get all three crystals! The orange one had me confused for a bit - I could see it from above, but didn't realize how to get to it. I thought the use of the limitation was good, but the level was large enough that finding the staircase first was a bit of a pain. There didn't seem to be a reset button, so I had to refresh the page to restart. Music and graphics were nice, seemed like something I would've played on PS1 or such. Nice work!
