Maybe just a QoL thing for a minority, but I would love the addition of a toggleable audio cue for pools popping up. Just a nice little blip/water splash sound effect when one spawns. Maybe another, different sound for when two spawn at once (BIG splash!)
In particular, I struggle when there's two pools that spawn back to back in the same place. I have very little input to know to react to them because my brain gets stuck on ‘well I just clicked that’. The ripples kind of fade in with everything else, and by the time my brain processes there is a second pool, I can be too late more often than not.
I find audio cues help me a lot with timing-based events, I'm sure it would be a great and fitting addition when the coders find time!
And, I do again think there should be an audio toggle for this for those who don't want to opt into this or dislike the sound of water splashing. I totally understand this isn't an improvement for everyone!
