My only suggestion is during testing check multiple display resolutions ratios. 1280x1024 and 1024x768 are 5:4 and 4:3 respectively, and account for most aspect ratios.
If the invisible restraints are the same in those two resolutions, it means they'll be fine in all of them. If they don't stay the same, you might have to suggest an aspect ratio in the readme for desired performance.
Also, have you ever played Shikigami no Shiro? (I believe that's how it's spelled) It was released as Castle Shikigami (or something like that) in English. Anyway, it's a vertical shooter like Ikaruga, but where you're weird demon hunter people who fly. It uses a precise vertex for collisions rather than the large area circle that Ikaruga uses, so the projectile patterns enemies use can be very tightly packed (and beautiful, really) where you dodge just barely between waves of shots.
