As an experment?
Ok, but why not use the alpha submission rather than submit it to the portal?
Suggestions however, are to make yourcrosshairs more visble and it would be good if the screen moved automaticaly tracking your crasshairs rather than using the arrow keys. If you can prgram the arrow keys and do hit test scripts you can also put invisible zones on the edges of the screen so that when the cross hairs moves over it, it will move the screen in that direction. Keep developing. Listen to what others have said, then come back when your ready to show off yournext version. good luck.
