This was a short but fun game, looks really great, i loved the artstyle even though it had minimal assets and animations. It really sold the ship atmosphere for me. The music was also perfect for the theme and the chaotic slashing, great job on that! I won on easy, but hard was too difficult for me.
I initially felt that the knife would move with the cursor on the y axis as well so was a bit disorienting to move the cursor but the knife only moving sideways. Other than that i would have liked to see more gameplay, but for a 4-day jam i can understand the restrictions! Overall, well done to all :)
