The sprites and animations weren't the best since I did them myself and I'm still new to pixel art. The ninja just canonically has a limp due to his injury lol, that's the explanation for the weird walk animation. Still, I think the style was unique, consistent, and better than what I could have got by downloading.
The intended strategy of moving towards an enemy and then slashing it at the last moment was why I used mouse instead of WASD for normal movement. The regular movement is slow as well as enemies come to you anyways and there aren't any stationary objectives. You do regenerate stamina when killing enemies, but it's a small amount. You also regain stamina at 2.5x the normal rate when still, so waiting for enemies to come to you while staying still is a valid strat. The stamina regen was intentionally slow to make sure you can't just spam slash to kill every enemy immediately. The enemies spawning on top is a genuine bug and I'll find a solution for it.
Thanks for playing and rating!
