Not wrist fatigue for me, more like my fingers are burning since I play on trackpad. Now I regret not having a mouse. BUT this was one of the most enjoyable games I had on this jam: VERY fast-paced, the kind of combat that rewards the player for just going for it, which is how it should be done. Noticed that damage is calculated based on speed so instead of swinging the sword a lot you can swing it slightly while moving and aiming. It's stuff like this that makes you feel like a real swords master. Also tell whoever made the music that it friggin slaps. Always been a fan of hip hop and rock 'n roll x shamisen or whatever traditional instrument you had there.
