Reviewing as of 3.1. First off, I want to say that I am a huge fan of old school dungeon crawler games, so this review may be heavily biased by that. I also want to say that the game is such a great example of the dungeon crawler genre that if the dev made a non-adult version of the game, it would probably do extremely well on the mainstream markets.
First off, the artwork is beautiful. The girls all look fantastic, and there's solid variety, especially thanks to the side girls(dungeon encounters). I actually really enjoy the dual art styles. The lewd scenes in sketch look great, and give a very sexy vibe, while the polished 2D portraits are very expressive and fit perfectly for dialog.
The story is well-told, funny, engaging, and creative. As some have stated, the pacing of the lewd content seems a tad rushed, but based on what we've learned in the story so far, it's explainable as a series of misunderstandings, intentionally poor communication, and the nature of Lily's curse. Dev did a fantastic job of organizing the story as a progression of "morning events"(daily progression), hangouts, and daily chats with the girls.
The actual gameplay aspects, such as base management, character(stats) development, and dungeon crawling are all beautifully done. I'm very impressed with the dev's ability to make such a complex game on such a simple engine. The dungeon crawling mechanics are inventive, unique, and fun. The only complaint I have, is that late-game scaling makes the dungeon far too easy. Hopefully dev can put some limitations on some of the abilities/stats that make endless dungeon runs so easy, and tweak the late-game resource drops(loot bags especially), as by the end of 3.1 I was able to earn enough resources to unlock every manor and character upgrade in a single dungeon run. There are some bugs, which is to be expected in early development, such as random event rolls having low or negative percentages when abilities should be making them easier instead.
The game is fantastic, and I highly recommend any fans of the dungeon crawler genre to give it a shot. The few bugs/issues(none remotely game-breaking) are nothing compared to the overall quality of the game. I am anxiously awaiting the next update!
