Tip: If you give a Muncher tile custom graphics, it will still act like a coin when a silver P-switch is active, whether it looks like a coin or not. So make sure to use ExAnimation if there's a silver P-switch in the area.
Here are my criticism for this hack;
You should use UV mapping, the DKC Forest Interlude needs a lot of work, especially those panflutes. I like the water scrolling effect that you did there. Also, you shouldn't let people fall into those holes on the wood with the small whomp on it that leads to the poison water. Also nitpick(don't take this seriously); The same aesthetics recurring, i.e the vine. You should add some landscape beneath the poison water so people just don't swim to their death. And the background needs some work, overall it was a fun hack, got 4 stars, clearly thought through level design and better than majority of hacks I've seen, keep at it BigBoo32 and 55SuperShadow.
My rating is 3 out 5.
