Thanks for the playtest! I didn't think about ultra-widescreen monitors at all while making it, so I'm glad it looks relatively passable.
RE the zooming sound: Yeah, it's a sawtooth wave. There are a lot of references to static and frequency in the game. If you use a controller, I feel like it's sort of emulating grabbing an antenna on an old TV and tring to find the signal, haha. But yeah, probably should have made that SFX quieter relative to the rest of the game, seeing as how much you have to deal with it (especially with the low base sensitivity).
Good point about having an indicator to show how random the position/velocity is, the pitch of the particle gives you a rough idea, but it's not immediately obvious where you are exactly along that line - especially in ball mode.
Glad you enjoyed the wackiness! :D
