You've crash landed on this strange alien planet, with nothing but a ruined ship and Carl, your trusty spider robot friend. Use Carl to traverse the planet and help get your factory up and running; along the way as you research new technologies you'll unlock new recipes to upgrade Carl into (optionally) bigger and (required) better versions!
This mod was heavily inspired by Xorimuth's Spidertron Engineer mod, using their code as a base and inspiration.
There are settings to control spawning with a remote, and also for adjusting the base movement speed of Carl (because they're slow). You can also choose to let Carl change in size as you upgrade him or stay a constant size.
