Firstly, I want to say that I'm really digging your podcast. Listening to other people's stories has helped me get through some difficult coding sessions where I would otherwise have rather printed out the source code, shredded it, then danced around a bonfire of the remains, shrieking madly to expunge the bugs and glitches that could only be supernatural in origin.
I hope to go back to Plumb Luck at some point but I would choose to start from scratch now. When I first started programming for fun again with 7800BASIC I had 2 ideas for a simple project to start with, the first being a Pipe Mania clone, and the other being a first-person dungeon crawler so of course I chose..... the dungeon crawler.
When people suggested I keep working on the '3D maze' demo I posted, I did just that, but I was still learning what the 7800 was capable of and how to actually program it so after a few months of slow struggle I was getting burnt out on the whole thing and needed a change. I went back to the Pipe Mania idea and that became Plumb Luck.
I do own the original Amiga version of Pipe Mania but I mainly based things on the Windows 3.1 'Pipe Dream', hence the grey and green colour scheme and simplistic look. Not having a Mateos cart at the time I had no way of testing this on real hardware so I was oblivious to how grey and green is just too difficult to see on the noisy, blurry, and generally disgustingly bad RF signal the 7800 outputs.
I deliberately didn't copy the gameplay exactly because I feel that if I did it wouldn't be 'mine', it would be somebody else's game that I just plagiarised. That's why the goal of each stage isn't to build a really long pipe that doesn't go anywhere, but to actually connect an input to an output.
I consider what's there to be complete, because I realised that I was sinking all my time into Plumb Luck and not into what would become Spire of the Ancients so I quickly gave it an ending, made sure it was playable, then dropped it as fast as I could. I have so many projects on hold until Spire of the Ancients is done but I will certainly have to go back to Plumb Luck and rewrite it to be how I imagined at the time, with different situations like plumbing the coolant into a nuclear reactor before it melts down, or completing a railway before the train comes along, and a mascot character 'Plumb-Bob' throwing the pieces on the board and commenting on your progress.
The experience I gained making Plumb Luck really boosted my understanding of the console, and I hope people get some enjoyment out of what essentially became a learning exercise for me.
