We're working on bug fixes for most of the stuff you've mentioned. I agree that the game throws a lot at you right away, and we'll definitely try to adjust that to give a better difficulty curve. Sound and music are also planned to be added, but we ran out of time since we were prioritizing getting the game into a playable/winnable state. Some images for the intro are also something I'd like to add. We'll be continuing to work on and polish the game, so if you're interested, you can check back after voting finishes to try an improved version.
Do you think you could elaborate about the game not going full screen on the monitor you wanted it on? Any information on how to replicate it, including how your screens were set up, what OS you were using, etc. would be very helpful.
