Some of my own thoughts;
the tiny-spider is far, far too fast. it's currently ~4x faster than a real spidertron while being cheaper and available much earlier.
The free robots are nice and I can see the need for them, but I think it should be reduced to only one port and a few logistics, with no construction; it's only 500 total blue science to unlock logistics robots anyway
Finally, I hope for the GUI's defaults to be based on the spider selected. As-is, tiny spiders have 1000 health, but retreat at 1500 or less not including shields. I'd love for these to default to 90% health and weapon range, for example.
Anyways, great work and I look forward to improvements
