UNDERTALE? I HAVE BEEN SUMMONED
I'm biased because of my Undertale obsession, but...here we go.
Decoration: 8/10
I really like that Muffet sprite, and the Meltdown-esque parts.
One complaint is that some of the deco overlaps the blocks in a weird way (like at the cube at 0:25)
Another thing that bugged me was the empty purple background during the Muffet fight segments. Maybe make the background just black or something?
Gameplay: 9/10
Pretty fun throughout, not too hard.
I like the fight segments 8)
You kept a variety of mode switches throughout, kept it intense.
Music Sync: 8.5/10
Could be better, but you did well enough.
8.5/10 Feature-worthy. You have a few rated levels already, this will probably be rated as well.
