Yeah finding the sweet spot for both shmup and non-shmup players is probably the most difficult thing. When I'm testing it's really hard to tell whether a section is fair or total bullshit. I always play with a controller so I actually have no idea what standard keyboard controls are for shmups, ZXC is probably terrible haha. And yeah I agree on the menus, threw them together last minute and the post processing is affecting them I think.
Thanks so much for playing and for the feedback!
