I finished the hack and tbh it's pretty nice!
Except that on the last level you can literally softlock yourself at the part where platform is going up and spikes throw you a ball towards you and in that place you can just fall from that platform, kill every Spike and just stay there because you can't do nothing until time runs out, don't do that!

In this hack i like that every world has different theme so it's not repetive and boring.
Especially World 1 Castle (and W1-A) this is my favorite level but the only problem i see there is that, if you enter the pipe somewhere in the middle of the level you can find 2 Star but when you finally leave the area, you are already in the bossfight and can't comeback so you could get 3'rd star.


Obviously i have too some problems with this hack like:
-Too many power ups that are not too far from each other
-Repetive star coins (By that i mean for example that few levels have indentical way to get a star coin like throwing a shell)
-Too close flag pools to those "stairs" at the end of the levels
-That softlock part lmao


Overall i think it's nice short hack and i do recommend to play it
