First of all congratulations for the game that i must admit is AWESOME.
But i have this problem. Every combination i try from the manual of the remote controller of the robot doesnt seem to work except for the selfdistruct. When i played this on my pc version i had no problem, so:
it may be a bug
it may be an enhancement of the Enhanced edition so ther's an hidden reason for the malfunction of the remote.
I hope someone could help
