to be fair i think u should remap the hard since it plays like a normal but without the rules of normal u can have bursts nd stuff in hard diffs but now its mostly just 1/1 sliders or 1/2 sliders
u can have jumps or small bursts etc in the map also i think the sr doesnt seem right to the rest of the set since it goes from a mid 5* to an high 4* as insane nd then a mid 2* on hard diff when it has much potentional to be a mid to high 3*
This isn't a normal diff. Major 1/2 gap usage doesn't mean it plays like one. Normals are usually composed of short 1/2 rhythm clusters with a lot of 1/1 breaks in between thus makes 00:39:516 - 00:49:904 - really straining for the player.
I would suggest keeping this as a hard diff, and making the SR higher by adding more active 1/4 rhythm (triples/bursts) to places like 00:36:920 (1,2) - 00:49:417 (3) - 00:59:777 (2) - 01:10:160 (5) -.
If you decide to remake this into a hard diff, the song length requires adding a normal diff for rankability.
things i spotted
Aesthetics:
probably some more but i mainly went to look at how the map looks like
Also OD 5.5 AR 4 is very low for an hard diff so u might wanna change that
