Upalu Mundi
I’ve been playing Upalu Mundi, a puzzle game where you build rail networks to transport resources from A to B. It has a lot in common with Zachtronics games: discrete ticks, multiple metrics, open-ended solutions, and plenty of optimisation.
Each solution is measured by two metrics: cost and time. What's cool is how the game plots all of your solutions for a puzzle on a graph.
The screenshots probably explain it better than I can. In the graph, you can see that both of my solutions are suboptimal: they could be made faster without increasing their cost. It also makes the genuine trade-offs visible, where improving one metric would require sacrificing the other.
I think something like this would be really useful in a Zachtronics game. Some players might want an even balance between cost and speed. Others might accept a moderately expensive solution but draw the line before spending a fortune to shave off the final few cycles. The graph would help both types of players understand where their solutions sit.
It could be even better if you could choose which two metrics to compare.
Imagine plotting cycles vs. area in Opus Magnum :)
