The immersion is top level! I laughed so much at the discussion of how you shouldn't tell the player they are bad, even if they're VERY bad :D Maybe that's why I had this piece of conversation twice :D
I would only probably love to have checkpoints more often, but that's because I am pretty bad at platformers haha. And it would be awesome to have some additional reaction for player doing something like dying/falling/going on the wrong direciton too often, but it is of course not an idea for a 48 hour game jam :))
