Just because the abilities are different, doesn't stop this from being yet another recolor mod.
Most of the abilities are just "jump, but different". Just different jump variants. You also tacked on a boost cause why not, even tho it totally doesn't fit Amy. This has the same problem as people tacking dash mode on their characters and thinking it'll fit their movesets.
Overall, not a fan. My recommendations? Original sprites, obviously. Also, maybe just change all the jumps to a standard spin jump, but while you're in the air, you can hold it to get a higher double jump. Finally, this character doesn't need a boost (or even dash mode). Not every character needs to be a speedy type.
