It's hard to explain, think of it as a Youtube video, your gif is the x1 speed and in my computer it looks like it is at x2 speed. It's hard to pick the bullet direction when you are playing this way.

Ahh well this may just be the default speed of the bullet... By default it has a fast constant speed but this may change in the post-jam release.
The way I programmed it, I believe that if you're using a smaller monitor, everything is closer together which could make it harder to play so watch out for that too.
I've already started working on a post jam version that should address some of these issues and improve general gameplay so hold on tight, it'll be out soon 😀
