Very enticing Story and Gameplay so far - taken the few bugs and the futile enemies (Ares and Simon) out of the assessment - more humping-options please - not so much into Vore myself, yet it would be nice to get a swollen belly from swallowing all of Lungo's "nectar", for example and not let so much of it go to "waste" ;-P ).
I can see that it's more Vore-focused though, and if that's your goal to make such a Ga(y)me, that's awesome for that community. - If you're trying to "serve" a broader/wider audience, I'd love to see some other kinks, too (for example: like cum [inflation] and all its possible effects - a lust demon must get pretty "strong" - if not even "out of control" from a certain amount, doesn't he?).
I'm curious to see where you're going with it and how you're gonna progress - and which audience(s) you wanna attract/reach/"serve" with it though...
Cheers and whichever it is, I'm sure they're gonna love it once its development progresses...
