wario land is a game franchise laden with potential for a srb2 mod, and this mod definitely understands that, but i don't think the execution is quite right just yet. i do like a lot of the (strictly conceptual) ideas, though.
first of all, the waft, shoulder bash and ground pound are all moves that are no doubt a perfect fit for wario, but i feel as if this mod misses the mark on all of them in one way or another. the waft, foremost, is a good double jump, and nice to have in a pinch, but its use is discouraged by the low gains on anything other than max charge, and the fact that there's no height gain option when it's at 0. i would recommend moving every charge down a peg, so that at any given time the player can gain some height, but would have to wait for the waft to recharge to go any higher.
the shoulder bash and ground pound are fine on their own, honestly. the bash moves quite a bit too slow for my tastes, i'd rather something about as fast as whirl's charge, but it's okay. i think my biggest issue with it is that it really doesn't feel strong, there are no special effects outside of a ghost effect that (if i recall correctly) only actually appears in wario land 4 while using the head charge. the ground pound, also, could do much better if it was mapped to spin instead of a button combination that sort of makes it an arbitrary inclusion.
other than that i have really nothing else to say, it's very much a mod that exists to me, with great potential that misses the mark quite a bit, but it is definitely a wario in srb2.
