Remember, in Screwball Scramble you control the maze, NOT the ball. Therefore when you press A (down), the maze goes down but the ball goes up. When you press P (right), the ball goes left, etc. Also: it does a low beep when the ball strikes a wall. It is very easy when you know these things. Basically start at the entrance point, press all the OPPOSITE directions, and wait for the low beep each time.
I was actually going to briefly flash the ball visibly if you hit the entrance point or the dead-end "X" at the top left, but there was some damnable bug and I gave up on that because I wanted to get the thing finished and submitted. Also the real game doesn't do that (though you might get audible clues from the rattling sounds of the real marble)...
My record for the whole course in my game remains 14 seconds (proper version) or 12 seconds (slow uncompiled BASIC, where you have ages to think about your moves). You do need a bit of luck on the "unstable table".
As a kid, I broke the blind maze on my real Screwball Scramble because I got angry with it. (And the hoop fell off just because it was badly made. Not me guv.) BREAKing is possible in most CGC games but not this one... it was compiled...
but if you want a reasonable review you need to send it sooner rather than later.
