I like this. It was fun, and when i started, I wanted to get to the end. A few things to point out:
Pros:
*The mash-up of the 2 games was a good choice, and style was well done.
*The animations on the characters were well done. Like Mario's costume moving as he moved, or how it looked like the koopa was actually shooting a bow.
*Nice progression the levels. Made it more challenging
*Cooldown's were smart, since we all know people can just spam weapon buttons for an easy win :)
Cons:
*Not sure if this is intended, but it seems that hitting the block is a bit glitchy. I cant hit it from the bottom, so the only way to wall jump off it from the side, and that doesn't always work.
*Hiding in the hay bales are a bit overpowered, because u can just take out the enemies while you're invunerable.
*Not to much a problem, but I would have liked to see a nice background, just because it would look nice.
But other than that, it's fun, and you have the mechanics down. You deserve that daily 5th place reward.
