Breaching into shrouded rooms fits the theme well. Gunfire and explosions feel very nice.
The hotline miami inspiration is clear, but the extreme lethality is far too punishing when resetting the level involves going through lots of slow motion segments as you breach into rooms. Meshing lethality with cool breaching slo-mo is a good idea, but I don't think it was executed correctly here. Plus, bullet collision issues (eg. bullet spawning inside a wall hitbox, causing them to instantly despawn) makes gunfights feel unfair and out of the player's control.
With a revamped slomo system and fixed bullet collisions, this could be a nice and fun hotline miami type game!
