Lovely in some part, but disappointed in others

Reviewed By: Timaeus on 12 Dec 2015

This hack doesn’t make sense to me, because most parts are new (music, level, etc.) but others are still vanilla (same music, some even with the same levels). For example, the first level, Quartz Valley is all new and the boss music is new as well. But the second level, Chemical Plant have the same music AND the same level, and the boss music is the same old one. That’s just BAD and make the game a bit confusing, but nothing that could break it.

I loved the new musics, especially both acts of Quartz Valley (especially act 2), the relaxing music of Aquatic Ruin act 2 (don’t remember of it does have a new name), metropolis act 1, the boss music and the level complete music. I LOVED those songs pretty much

The levels are very well done(the edited ones), but why metropolis have to be that hard? Any false move or rush resumes to death there. The Air dash made the game a lot enjoyable and easier to move around. I like it as well.

This hack is a more and less thing,but the edited parts of it already makes it a GREAT HACK.Play it.
