This is a pretty solid submission. I like how you interpreted and implemented the jam's theme in different ways.
At first i didn't know straight away that you could change levels, until i looked at the game page's description.
I love that all three characters have different base attack and a secondary attack. Personally, i liked the samurai's moveset the most.
Nontheless, when changing the map there is sometimes the problem that the player charakter is stuck or dies instantly. Which is very frustrating.
But overall i think you did a great job with your game.
