I quite like the trailer you've shown, the levels looked pretty good and fun to play, but there were a few things I have noted:
-In the last desert level shown, the NPC replacing the Ninji has a broken death effect. That's not a good thing to have in a trailer.
-There are at least 3-4 levels shown that require the usage of switch blocks. I'd be careful with this gimmick if I were you, it's a very overused gimmick and many people tend to frown upon it being overused.
-How many levels have you actually finished? You haven't updated the worlds list. Also, there are a lot of levels you've shown off in both this and previous trailers and screenshots, I'm just worried that you are doing a Mario Kart 8 where everything is revealed before people are able to play the game itself. Are there any large amount of levels that haven't been revealed in some way yet?
I still like where you are going with it, and hope that this project turns out well
