Kind of regret playing this right away because it was actually pretty good. With most shitty Ren'py games I just play them for the porn because the story, dialogue, etc. is p. garbo with a few exception like Four Elements Trainer. This, however, played almost like an actual JP VN and it was p. fun throughout despite no sexual content. My favorite part was the diversity of the girls. I love flat chests the most, but I also enjoy medium and big chests too, and to often do games only ever have women with giant tits. Having women of all kinds was a nice change of pace, and the dialogue and choices were pretty funny.
I hope this gets of the ground and you're able to make more, because so far you've done a great job. My only advice to help it is that, when you do get to the H-content, you should definitely look into animation. Even if it's not the best, most fluid animation anything is better than nothing in the case of moving pictures. The only thing that can get away with no animation are 50+ hour VNs that get you invested in the characters, but even then they have voice acting to help sell the non-moving CG. I like everything else so far and I'm sure you already have an idea of what to do, but I figured I'd give my two-cents because I don't want to see you mess up on the most important part.
Oh, and I'd also suggest making a $1 tier for your Patreon. Believe it or not, there are much more people who will donate only a dollar than there are people who will donate $2. Those single dollars will also quickly add up and it wouldn't hurt to introduce more tiers, like a $1, $5, and $10 tier instead of the current $2 and $7 tiers. It's what more people are used to and most people don't like change, so if they see something familiar and cheap, it may change their mind on not donating. Some people also just don't have much money and want to help, but may see $2 and think that's too much. It's weird, but that's how the mind works.
