Thank you! The idea of the class choice is it determines your starting moveset (2 attacks), and you would unlock the rest randomly over time as you use your sword and "level it up". However due to time, they're just all unlocked from the start, so not super meaningful choice.
I actually prefer how it looks in motion, it kind of increases the fidelity as you get an illusory average of the different frames. Plus it feels like it twinkles. But I imagine it's very YMMV; there's some attempt at dither stabalizing I attempted but it's not very good and requires a certain sweetspot of mouse speed. And by nature, only works on looking, not moving. Definitely something I want to focus on improving after the jam, but it's a non-trivial issue.
