this is some really solid work. i really enjoyed the spritework and music. it feels like it really embodies the spirit of older FNF mods and i mean that in a good way!
there are very few gripes i have, so i thought pointing them out would be good for future work on this, which i truly hope to see.
i did enjoy the music a lot, however i felt there was some vocal imbalance with the instrumentals. the first song did very good at making sure you could hear the vocals and the instrumental clearly, however in the second song i found the vocals a bit quiet and in the third they were very loud. ascend and descend are still very good songs, but i think a bit of mixing could really make them the best they could be.
The difficulty spike between ascend and descend was a bit jarring, especially since it is only the first week, i'd recommend having the charts and gimmicks steadily increase in difficulty rather than a random spike into difficult territory.
that is all i have to say though. this is some really good work, and i truly look forward to the next update. keep up the awesome work dude!
