I was bored today so decided to test your creation :
- The airplane part:
I wouldn't put randomized sentences for the boring seats, people love tends to explore as soon as they can, having personalized sentence to each seat would be good fluff in my opinion (but not really a priority).
- The beach part:
dialogue tree doesn't let you select both, wanted to find out what the other said :(
- Exploring around the camp part:
Having to use another button instead of the default use key to capture is a bit weird.
- The training part:
Do the brain scan do anything atm? also, what does the purple button actually do?
Making some tooltip maybe necessary, didn't know what each button did before checking them one by one.
- Overall
Dialogue tree need a bit of rework (as not all the options are sometimes displayed after you finished one, thus needed to click one you may have previously used to display the one you want).
The captured persons model have a texture seam between the body and and the head, it's a bit weird.
Overall, it's a good start, go at it slowly and I'm sure you might achieve the result you want.
