Btw just my two cents, I played it with mtool, I can only recommend this game. This has actual gameplay elements, different routes and optional secret NTR scenes (if u choose to not see them, only from the main hero's perspective) and even contains a pure love route. It works with a questing system, meaning that u fulfill requests (and sometimes special requests aswell) until u can rank up with a final mission. I have ofc just tested it in the beginning but this one looks like alot of fun (considering the cgs and standing pictures are also animated). The translation from mtool wasn't the best, but it was definitly playable, so this one I can definitly recommend!
EDIT: This one seems not unreasonable to buy either, 12 USD and it looks like the content in this game is pretty good, so not one of those 30 mins games which get released like 1000 times per month
