There seems to be a least one viable alternative solution. Am I wrong? [The middle "3" on the left can extend one square to the left and one square up (instead of two squares up), the "5" then can form a solid "q" rather than a 45 degree "m".]
No, because to form a 'Q' shape you'd have to have 6 squares in the 5 region. Otherwise (a) you can't form a Q in the first place, and (b) you would have at least one 2x2 area fully shaded. So I suspect (from what you say) you had 6 squares in your 5 area.
Although the nurikabe on puzzlemix are completely handmade, I did write a solver for them many years ago which I use to check them - so I would be surprised if any of them had multiple solutions simply because it has been tested repeatedly for a loooooong time.

I guess this Q was shaped like a 2x2 and then another square was added in the south east of that. But that would look like a Q, but it wouln't be a connected area (diagonal doesn't count).

You are right! Thanks, Gareth. I think my high temperature is making me loose the ability to count properly ;). Much appreciated. I am cool ... really.

Key
A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
