Hey there, just tried this yesterday and gotta say that I'm a big fan, even if I'm usually not super into vore.
I'll join Green in saying that the EXP feels a little wack at the moment, though balancing is never easy when it comes to games, and I have to say that the progression system is looking quite good already, so you're like 70% of the way there already!
It definitely took me a second to get used to the controls, but I really appreciated that you gave us the possibility to remap the controls, even if the UI buttons stay the same (that's a detail, really). Once I had stuff the way I prefer, getting my head around the controls wasn't really hard, though I was a bit confused by the fact that pressing yourself into walls lets you jump higher sometimes.
Anyway, I do wish that belly rubbing were mentioned somewhere, since I went through the levels without ever realizing it was a thing, so I played the vore version of "Waiting for Godot" a lot.
Overall, I also really liked the amount of customization you gave us (God how I love when vore games have some WG) and the art is lovely, down to the sprites themselves.
Now, besides just giving general feedback and praise, I wanted to ask if you need any help at all with writing, be that dialogue, story planning (if you want one, anyway) or any such thing. I've got experience in writing for games of many varieties and do not ask for money when it comes to helping out on things like these. I don't want to bloat this message too much and it's kinda awkward for me to extend an offer this way, but if you're at all interested I'd love to discuss things further with you.
