Crysilis is the second level of the episode The Final Clash from Jazz Jackrabbit.
Once a barren wasteland, now a shimmering gem in the night sky. Crysilis is Devan's depository for all of his (stolen) treasures... Time to raid it!
Crysilis is likely the hardest stage in the game, due to the tricky platforming which requires a lot of precision and lots of Loo Guards sniping you from above and Golden Bouncespikes blocking much of the path. The first area is a huge maze with many different routes, while the second area is one huge walk in a circle. Once again you will have to deal with spiked floors, as well as moving springboards which you'll be required to use in many sections.
