honestly not too difficult. a good madness game, but a stereotypical hotline miami fangame, where the level design has a focus on racking up a high combo, over having interesting enemy placement that forces you to think. the levels arent challenging, in spite of their enemy counts, and are really, really short. playing melee only isnt a challenge either, as enemies just run into you, and most of them are placed in teeny tiny rooms anyway.
but, the modifiers (especially chaser) do give you quite a bit of replay value, altho realism isnt an issue if you have a route in mind and drunk is just annoying. idk what berserker does, and real time didnt at all impact my playthru since i never once pressed C. so yea, cool madness game but sorta lame hm levels
