This was actually one of my ideas for the theme, so I'm really happy to see someone did it. You did a great job of explaining the mechanics in the beginning, and the difficulty ramp starts out well, and I feel like I'm getting it, but I think the problem is that your levels get too big too quickly, so restarting the more difficult ones is more punishing, because there are so many variables to test in one run, and so then your flow is broken and it becomes a bit discouraging. Overall I think you nailed the mechanics and the theme, and it would be interesting to see this game with a more welcoming difficulty curve.
