This is great! I love how short and snappy an experience it is.
The dash really saved me, but it was the only input I had to look outside of the game to discover. Maybe adding a quick notice in the game listing the inputs would have been helpful.
I love how there are $1000 hats, but you can't earn any money... that was pretty funny.
Also, the idea that those guys won't duel you because "no hat" was funny too.
Good work!
