Basically an alternative version of Rondo of Blood made for a less capable platform, expect downgraded visuals and music, though both are pretty good on their own.

Not bad at all for a few stages, but then devolves into being one of the most frustrating games out of the Classicvanias and for no good reason either seeing how much more well balanced Rondo is, and it's not like that's a walk in the park either.

If you only have time to spare to either play Rondo or X definitely play Rondo, otherwise it may be worth to give this one a try too if you're curious about the differences between the two.
