Cool style that the game is going for, it made me think of the game "Not a Hero", and the intro dialogue paints a cool and brutal picture about the game's world, and when I say brutal I mean it lol, the game is stylish but also veeery hard, which in some parts made it a little bit frustrating, especially after death because the checkpoint is too far behind, which made me play in a "cheesy" way, in which I would pre-fire before enemies got on screen in hopes it would kill them before they shot, which worked, but it made the game's strategic cover and shoot combat less fun, since I had to memorize the enemies location and fire away before they appeared, perhaps making hideouts more common or easier to take cover could help, or increasing the players health, maybe by regenerating 1 HP after killing an enemy so better playing skill is rewarded with a longer healthbar, and if you take too many hits, at least you have 1 hp for the next enemy, just some ideas. Also it seems that some sounds are missing like shooting and reloading.
But overall, this is a very stylish game with a different take on the common metroidvania gameplay, which is very cool. And it also has a lot of potential if it was more polished and rebalanced, especially if the game had a synthwave soundtrack, it could fit very well. So congrats!
