Unfortunately I could not get the game to run even with many restarts but I was able to access the pause menu so I can give some feedback on that.
I like the layout of the menu as it is very clear and uses some great HCI techniques.
I would suggest implementing some feedback when the graphics settings are applied as at the moment it is not clear that the options have been saved. Also if the player forgets to press apply before leaving the menu there is no prompt to ask them if they wish to keep their changes so they are lost. I don't know if it is a bug but there are no sounds in as part of the menu or background music. Having this would add an extra layer of feedback.
The video of the game looks great though and I would like to play it if it would run. Hope this helped somewhat.
