Really appreciate the reply, would have gone crazy not seeing a clean solution; now I'm sitting here like "Why didn't I think of that..." I think I convinced myself that splitting them all into their own tracks was going to be slower due to longer reroutes but clearly not. I think the systems are good; there's some learning and some tinkering, but I was able to get a pretty good understanding even without any direction from the game. Like for this level at first glance, one big ring through all the nodes looks like the fastest solution -- it's obviously not and I assume that's because the cars are slowing down the ones behind them as they spawn through nodes. This isn't a knock though, it's actually a good thing; I'm able to figure out the systems through gameplay instead of explicit guidance. Now obviously there's a balance to be had between the two, and that could be found through iteration, but even the presence of that dynamic is laudable, especially in such a short time frame. It's only because I got so obsessed with this game and that I like it so much that I've noticed some of the hidden, unexplained things (seemingly cars don't have to go through every node of their color, just return to the starting node) that both frustrated and intrigued me. The more I thought about it, the more this feels like Poly Bridge than MiniMotorways. I can beat a level with endless tweaking and optimizing, but sometimes you need to step back, scrap a whole idea, and start fresh, and that is very, very, very cool. Anyway, thanks for making the game and sharing it, if it's not clear from my rambling, it's awesome and I love it.
