LISA.
The asthetic might be off-putting at first, and the difficulty can be annoying in the beginning of the game, but you get used to it. The music is exceptional, and I strongly recommend not save scumming.
It's actually a trilogy, not just the 1 game on steam. The first part "LISA: The First" is a free download and WAY different from the next 2 games. Very important for context tho, and only takes about a hour or so. Go play it.
The second game, "LISA: The Painful", or simply "LISA" on steam, is the main meat of the series. Go in blind after First. Don't save scum. Enjoy one of my favourite games of all time.
And finally there's "LISA: The Joyful", available on steam as DLC to Painful. Don't even look at it until you finish Painful. It's a great end to the series, in my opinion.
And again, the music is amazing. "Bloodmoon Rising" is probably my favourite ost song of all time.
