I've been a huge fan of Ib ever since I saw a playthrough of it (so probably like 3-4 years at this point) and was super curious to see how this would compare to it, since it's obviously stylistically inspired by it. I loved Solm! You could see the inspiration from Ib in the art and atmosphere, puzzles, and even some of the events, but its storyline was fresh and novel. It definitely wasn't a cookie cutter genderbent version of Ib like I was dreading.
It's definitely shorter and the puzzles may be a bit harder, but if you like Ib, I don't think you'll regret playing this.
