just wanna know if it does

It would be difficult af but that's in the spirit of speedrunning right? plenty of incredibly difficult popular speedruns, I'm sure somebody would do it, eventually

It would be simple, you'd just have to get perfect on every level and 100% all bonus levels, I think it would be nice.

This is for the single level run anyway, it's not very efficient to reset a whole game run every bad fish spawn

They can so if you don't get a good spawn with the enemy fish it's best to reset immediately. I seem to get the fish in the bottom right where I want it the most by going to the absolute bottom right and then scrolling the screen a little bit to the left and up, the fish usually appears around the 7.5-8 second mark, and if it appears at like, 10 seconds, that's also a time to reset.

You seem to be able to save a good second or so on sandy shoal if you wait in the bottom right and the fish that will eat you spawns right there, it takes half a second to a second ish to go over to the left or anywhere else if they spawn away from you, so you can save a bit of time if the enemy fish spawns right next to you.
