SMBX2 Level Showcase : Throwing hammers at the Piranha Plants!

Hello KZbin!
This level today is an i had idea during the week, and so I decided to share it with you!
This level on the beach uses the hammer suit and piranha plants, throughout the level you must kill Piranha Plants to advance! There's also an underwater section because why not. There may be something to adjust but I accept all suggestions and criticisms in the comments!
