Really good implementation of the Hotline Miami formula. Game is tough for sure, but definitely feels fair.
Some weapons were way more OP than the others. Would have loved to see improvements and other ideas on the formula, rather than just the same mechanics.
Music is really good, and sound effects are impactful. Art is pretty simple overall, but feels pretty coherent, and the post-processing effects make the game feels less flat and adds some flavor to it.
Overall a solid entry, but yes, like the others have said, better theme interpretation would be better.
