im sorry to hear that, about the job interviews.
but dont worry, you will make it, my friend!
just stay strong and focus on getting a quick job/a cheap accomodation for yourself...
as for the problems with the new technology of the game, i think that you've aimed too high for the new project...
you should try for a more simple approach to the game.
think simple.
in yare 3, instead of making complicated things, just do things like yare 2, but with a twist:
add more 3D characters to fatten up.
a centaur girl, a spider girl, a few monster girls, a werewolf girl, a minotaur girl, an orc girl, a fox girl, etc etc
just use 1 room/environment for each girl like in the character select options of yare 2, keep things simple, and you will be able to make a successful game.
do that, and you will manage to do a very good game.
complicated plans often lead to more difficulties, so if you will keep the game simple, it will be good.
