First of all, I think the game has great potential, especially for time travel scenarios.
I mainly play in a windowed environment. I have twice killed the game due to the game’s use of an X as an in-game window close button. I would suggest that you do the following to prevent that from happening in the future:
Create a hook so that when a player clicks on the X for the game window, it comes up and asks if they really want to close the game window.
It might be better to use a button that says CLOSE on the bottom of the window to differentiate it from the game window close button.
Also, just a note: I have had issues with hatchets/axes getting “stuck” in my character inventory (not being used as a weapon). They usually get stuck in the bottom left hand corner of the inventory. I see it, but the game doesn’t seem to recognize it is there. This isn’t a complaint, I just thought you might want to know.
