It's an indie pixel-art Metroidvania so it might be easy to just glance over, but I played Rusted Moss a bit ago and was really surprised by how good it is. I wouldn't say I play a huge amount of indie Metroidvanias like that, but I don't play an insignificant amount of them either and it really stood out among the crowd to me, so I would recommend it if you have any interest at all in playing a Metroidvania.
