This is a neutral recommendation. The gameplay is solid, metroidvania-style spaceship shoot'em up. The puzzles and fighting can get rather difficult at times, but never unfair. If you fail a few times you will recognise patterns and you'll eventually get it.
You end up getting about 10 different weapons to play with, but the ones you get near th end of the game end up being just utility/physics in a very few niche situations. It just seems to work that way with these type of shooters, and it doesn't really change gameplay dramatically enough for any refreshing changes. One thing I like to see in metroidvania games are mobility abilities and this game lacks them.
The game tries convey a story through very short cutscenes and gameplay and while it works at getting the story through, it didn't work well at making a compelling narrative. I would have preferred some dialog but I can see why they choose this style. It just didn't jive with me. Same goes for the art style. It works well for the game and is unique without being 16-bit pixel indie game graphics, but I would have preferred more colors than black in every scene, even though you are on a "shadow planet". Just personal preference, I guess.
