Your patch still has issues: you can't walk in the overworld, since you didn't put the green paths. You only made the GFX of them. Since it was an easy fix, I fixed your patch myself and gave your levels a go.
I was disappointed to see that, in reality, the only level different from the SMW ones is the first one. The rest are all levels from the original, which I didn't go trough for obvious reasons.
The level this hack is made of is kinda linear, but it can go. The first half was okay; I don't really approve of the use of the parachute enemies when the ground is very close to the top of the screen, especially if this level is meant to be a first level of a hack. The zone around the midway point is abrupt
, I would use proper ground tiles to avoid small cutoff created by the pipe and to make it look much better overall. I'd fix the midway point as well, since you only added the part with the white line on it.
Second half was quite boring. It's pretty much an empty sky, with nothing but population enemies going on. I also point out that the P-Balloon has wrong tileset
. There is a 3-up moon, which I'd remove if I was you, since it's meant to be an extremly rare item; I'd also stick with the normal goal point question sphere rather than having mole dirt and calling it "emerald".
There's nothing else I can say aside from this level, since the rest is SMW levels. Please, make sure your patch works as intended before you submit it here. Plus, make sure you have atleast a world of levels before updating the patch: it's true we can test one level at time, but I wouldn't recommend that, since most testers could get uninterested.
Hope this helped. Good luck with it.
