Cool little game with a great implementation of the exchange theme! Really like most of the weapons, the spear is most satisfying to wield. The vulnerable dash is the main thing that was ruining the fun for me and on the second and third boss not really helping to dodge their attacks.
The difficulty spike on the third arena is too much for me, so sadly I didn't finish the game, but it's good and with a little tweak in balance it would be great!
