Verdict: 2.5/5
Very strong CGs, maps, story and the premise. VERY weak mechanics and undercooked characters.
Not only is the game (personally) even more annoying to grind than Nebel, the reward is laughable by comparison. There's barely any "live" content where you can watch Trina in real time like you could with Kana. No cameras-esq events are understandable but toilet, alleyway, onsen, bar like events from Nebel could easily fit here. You only ever find out what happened (at earliest) the next day after crafting the CG and trying to remember which of them is new, which is just boring.
With a lot of the content being inaccessible "in the moment" due to being either not shown or blocked by maids, doors and other macgyvers, you're only left with a few pixel animations that are shown in very few select scenes (brothel, prince ending etc.). Also, don't get me started on the overly complicated (for no good reason) status page that doesn't update the cum textures aside from her womb and requires you look for bracelets that unlock it portion by portion. Trina got sprayed once? Good, now it's going to show up on her till the end of the game. Also, she's gonna have a perpetual facial as a bonus.
I think the game would benefit from fewer characters. There's a lot of content but it's spread-out across too many characters and Trina's states that it feels underwhelming. The prince, who is supposed to be the main NTR draw of the game with "Nebel" like gameplay, was the most disappointing. The only part of Nebel I saw in his section was the choice of "Don't call out to Kana / Stay out of it (Trina)" which isn't something most Nebel fans would consider the sauce that made Nebel so popular.
In conclusion, grind, grind, grind and then watch what happened 2 days ago is how I would describe this game. BBQ is peak game-maker and I will support their every release, but my man, this just wasn't it. Looking forward to the (possible) DLC.
Sorry if I come off too hard, it's a great game if all you want to do is sit in recollection room.
