Update! I might actually drop it here today, I need to get the H-status screen finished, but that's basically all I need to do! (Can I just say that whoever made the H-status screen have hearts in the background needs to step on a lego brick for like a second because holy shit is it annoying to edit the textures in. Anyone have any software that's good for this kind of thing?)
Anyway, here's a couple of tips about the game!
The game is simple: You level up in the game, you get more scenes. The RPG battling element is completely unnecessary if you want to access all the CG's though. This is because there is an item in your inventory labelled "Max Crystal," which caps out Yuuto's level.
In total, there's about 10 scenes. seven of them can be accessed through the game by levelling up.
The other three take a couple more steps:
For the 8th and 9th CG's, the cat will tell you to get "Proof of Pregnancy 1" and "Proof of Pregnancy 2." These are gotten by playing the 3rd and 5th CG's at least twice respectively.
The 10th CG requires you to have an item from the shop that costs 50,000 gold. You can get this gold by playing the 6th CG, where Fuyuko prostitutes herself for money.
I haven't tried out the battle system, but I did try to translate what the game had to offer. If there is some Japanese here and there, or some of it is jumbled, then my apologies. Anyways, I'll drop it here soon!
