Yes I am using the V0.4 release and I did see the disclaimer at the beginning but I want to state problems now so they don't go unnoticed on the final release. I cannot get out of the Avian selection. It just crashes out the game. And unlike V0.3 I cannot get out of the game for anything else which is a bit more disappointing
For the crashin have you tried this tutorial: https://forums.amorousgame.com/threads/how-to-run-amorous-without-it-crashing.1075/ ? For going out of fullscreen press f2 to go to windowed mode when in the game.
The problem is you can't really edit the fursona without the game crashing, Just pointing out what Randomness-Wat said. You can still run the game without crashing, you just have to stick with the default character. I recommend just waiting till the problem gets fixed if you really want to play the game with a custom fursona.
I was just asking since it looked like he meant that he crash regardless of picking the default character or not.
