Are these sprites custom made? They look pretty decent.
The skin in general is pretty good, most sprites don't look bullshitted, and I like that he's in his officer uniform for fire flower, that's a nice touch. However, I must note a few of things regarding the sound effects.
1. Don't duplicate sound effects, the game will automatically load from the base skin if you don't have something on there.
2. I'm one of the few people who like voice clips as I think they give the characters more personality, but the only one besides selecting him is him shouting every time you spin and that gets annoying very fast.
3. is the fireball sound supposed to be a gun shot? If so, you should probably find a better sound effect...
edit: I just realized there's more shouting when you die. Yay.
