1, There needs to be more practical application to the lust mechanic since as it stands it only impedes additional options for sexual encounters, and I kept going to the jungle to find that flower scene just to bump up to 50.
2, Having a hint as to what choices will result in immediate sexual encounters would be nice. Not a frequent issue, but I was not expecting "Halt" to immediately go into vore.
3, The sizes could do with some readjusting as it's a bit odd to have a 8 by 4 dragon with a dick less than three inches.
