Firstly, incredible work on this game, you've clearly put a huge amount of time and effort into it. Huge respect, and looking forward to the update.
A couple of ideas, if you're open to them...
- When the player character is fattened into Dizzy's, maybe add a few more dialogue choices/text varieties for the 'passing time' options? Also some more pink text stuff about how the player character is feeling, eg, when their flab hits the walls for the first time. Similarly for the girls you fatten into Dizzy's. While I'm a big fan of the way they eventually stop interacting at all as they approach super-blobhood, having some rare or unique reactions to their situation as they continue to grow would be cool.
- Seconding calls in the comments for more gassiness! You've done an awesome job with the audio cues in the script, love the gasping and wheezing, but especially for characters with the 'slob' personality adding a bit more slobbiness would be excellent.
Obviously I know nothing about game design, but these are just a couple of suggestions!
