Cleared X Challenge in normal mode

===
The collection itself is well put together with some really nice extras, and the soundtrack remixes are really good too. Although the Day of Sigma OVA could have had more audio options other than the english dub...

The X Challenge mode is such an interesting concept, especially when both of the bosses work really well together (spiral pegasus and neon tiger come to mind), and it's a fun time at least on Normal difficulty.

On Hard, stage 2 is a nightmare as expected, and the increased boss HP makes the whole thing a lot slower and not that fun.
