I really enjoy this. I have some minor issues however:
~ Looking in other windows while the game is active totally locks up the windows os. This is something to possibly look into.
I can't seem to find the reason or way to replicate how this is happening. Attempting in using any forensic tools to analyze behavior for errors is just freezing the os.
~ One of the controls is using the "Alt" button. This is something I had to change since "Alt + F4" or "Alt + CTRL + DEL" are system based shortcuts.
Having alt in the game cuts off the system shortcut access when the app is frozen.
