Look's really nice! How many worlds/levels will there be in this?
Eight, to be exact.
Hey, this seal looks familiar!
(this is the dolphin replacement by the way)
There are lots of piranha plants in the final area of the level. Throw your eggs properly and they won't be a problem.
Here's a demo patch for testing. I don't know if I should make it longer or not; right now it ends at the end of the fishing boo room. Too short? Too hard? Too easy? Feedback would be appreciated. There's a secret exit as well so keep a look out for it.
