I think you have a really good start here. It's certainly short, so I'd love to see more added. I saw that the idea is to try to aim for the least number of steps. I think having a few more tightly designed levels with less/no RNG might help facilitate that idea. Adding in a final score screen (or even a high score counter) would also help incentivize optimization.
