There is a lot of juice, polish, and style in this entry. Even the itch page is gorgeous (That floppy disk thing is sick). Visuals and audio is really fantastic, and even things like the movement tweens on stairs feels really nice when playing, not to mention the box and character art. Wow.
I did run into one bug where I got a white screen while talking to the cat sailor and couldn't progress, not sure what happened there but it didn't take me long to get back, and other than that the only feedback I would have is that it's nice to be able to strafe and turn without holding down shift (QE for example) and hold down movement to traverse multiple grid squares, but those are very minor preference things for me personally.
The duality mechanic is implemented well I think in the karma system as well.
Would love to play chapter 2 and beyond, I really hope you take this forward.
Awesome entry, great job!
