I really like the art style on this take of Mario Maker. It's got a nice pirate theme. The starfish looks a lot like Patrick from Sponegebob Squarepants :) Level editors are truly difficult to build - I've built one myself for a game in the pre-Unreal days. It has enough building blocks and size to truly build some unique and interesting levels. This was a great idea for a game dev level design challenge. There is one bug I found that not sure if it is actually a feature: If you jump into the moving platforms you will sometimes be launched backwards at a decent speed.
