Wait, you made all voices yourself? Oh my god, I'm so sorry. I thought you were just some guy that paid some inexperienced ASMR VAs. With that assessment it's actually not that bad, just needs a lot more training and trying to put more emotion into it. For example Iris sounds very flat like an AI voice. You'll got this someday. :) Just a tip: Build yourself a soundproof VA booth, if you're insecure about your voice acting and just scream. Without confidence, you can't voice act. If you're insecure about asking a male VA, try researching how men can talk deeper so the filter is not so prominent.
The notification happened every time. I got the same strip scene multiple times per week. You could debug it by disabling the condition and to see if it actually shows the notification.
I see you have a lot of ideas about the DDR style mini game. I'm eager to see what things you have planned. And it makes me happy to read your passion. Always remember that incredibly fast gameplay that is easy to execute with one hand (because you know why) and requires no thought is the best when it comes to fetish games. This is one reason why Cowtastic Cafe on Itch is so popular. It's fast, easy and instantly rewarding. Weight Gain games is all about progression and testing the limits and getting motivated because you see how big they grow.
And tbh, I'm a sucker for unrealistically big sizes like making her huge and immobile in the vain of Chub Chomp Chill, if you know this game here on Itch. While it's hard to implement it narratively, you did hint the capacity remover at genesis' shop. But I'm not forcing you into anything :)
