Hey there! I played your game and I think you're doing a great job so far! I was very impressed with the art currently in the game!
I am personally a huge fan of oral vore and the likes. I love to see mouth play and tongue movement, as well as slurping and expressions. The emphasis on the gulping and lip licking are also awesome to me. Both internal and external views from the giantess's maw would be incredible!
Good luck on the future updates! And congrats on the launch!
