Short, buggy and frustrating, there's not much to recommend here. Story is simple, you're a demon policewoman investigating a string of disappearances. You investigate a warehouse and a water treatment plant (both on the same map and nearly next to each other), beat up the ring leaders, game ends.
The combat is fairly standard battlefuck but there's not enough effort put into it. You can't level up, you can't swap most of your gear, and enemies only drop healing items which probably won't even cover the health lost in the battle. Avoiding it completely is the best option, but if that's what they intended I don't know why there's even battlefuck mechanics.
Three animations for the two player controlled characters and a couple of cg scenes. The scenes are very short, one in particular just saying "and then they got fucked forever" with no more description. There is a gallery, but one of the scenes there softlocks you, so I hope you saved before clicking anything.
Which brings me onto bugs and weird choices. For a start there's no options menu, the usual spot in the menu is just a blank space. Hope you enjoy holding shift to run, oh but don't do it too much. Running over one area in particular confuses the game into thinking you're on a different elevation, so you run into invisible walls until you go back and walk over the bugged spot. Also don't hold shift as you exit cutscenes, since that seems to replace your running speed with your walking speed until you hit the next cutscene. The battlefuck animations also break sometimes, staying on the screen after they should have ended.
TLDR: One hour not very well spent. None of the scenes have enough substance or build up to be worth it, bugs were way too common, combat is slow and pointless.
EDIT: I have been corrected, there is no options in that menu by default in RPGM XP, the removed line was for formations.
