Thank you for the post and your interest i'll try to address all your points here.
1. There are more vore stuff as the game goes, but don't have stuff for the internal view, as its mostly a mix of all kinds of size/giantess stuff, so trying to include a range of it throughout.
2. There are later moves/etc. in combat that allow for Vore/Stomp/Etc. kinda like finishers that aren't in this demo.
3. Sadly that is the end of the demo at the elf tent, there is a bug that makes it so the Dialogue saying that didn't fire off. But that is just the end of the Demo ACT I as it stands. I'm currently working on ACT IV.
4. I've considered it, want to get a full working act one hammered out, everything, art, sound, level, etc. how I want it before putting up a patrion to fund the rest. But thank you for the support, and hope you can enjoy and share around. The more input the better game i can hopefully produce. Its just me at this time and i have no idea what i'm really doing :p
