This puzzle appears to be broken. After h5+ Kxh5, the puzzle gives Qf3+ but I think that Nf7 also works. After Nf7 my local evaluation gives +2.3 to start and fluctuates a little, giving +2.9 in the end (depth 36, 7 threads, 256MB memory). I'm not sure what the exact cutoff is on when a position is winning (in lichess puzzles), but I think this must meet it.
(The reason I'm posting here is the thread https://lichess.org/forum/lichess-feedback/reporting-puzzles and I can't find any more recent update)
It's not wrong, Qf3 is mate while your move is only +2/+3
I know puzzles are supposed to only have one good move, but Qf3 is not hard to find and mate so in my opinion your move is a blunder. Nothing less.

The goal of each task is to make the best moves. The best moves lead to checkmate. Any other winning moves are wrong.
Neither of these responses are helpful. Every lichess tactic is meant to have exactly one winning move in every position you're asked to play in, and my point is that there are two moves in this puzzle in this position. It doesn't matter how good they are relative to each other.
It says "find the best move" and mate in 4 is obviously more bestest than +2.9

Yes I played it out that is true
