Sorry about not being able to rotate the camera! This is super important when you are building. To rotate the camera, you have to hold down the middle mouse button and drag the mouse. This means you are out of luck if you are using a touch screen, trackpad, or 2-button mouse. As a macbook user, this is definitely on my list of things to address before release.
Right now, motors are not modeled in a realistic way. We have just taken guesses at things like torque and speed to get something that looks and feels close enough for now.
Over the coming months, we will be adding components and figuring out how specifications affect gameplay. I am hoping to include real-world DC motor specs like rated voltage, no-load speed at rated voltage, stall torque at rated voltage, and max voltage. Battery ratings would be things like rated voltage, max current, and amp-hour capacity. Of course, all of this is subject to change if it turns out to be too confusing for players.
Once we get the mechanics of this working in actual gameplay, then we will put together documentation for everything.
Apologies for the long-winded response, but hopefully it provides some insight into where we are and where we would like to go.
