Spent a bit of time playing around with the basics, enough to get a simple recharge station going.
The UI and UX are... really really rough for the start, since not much is properly explained.
As an example, attempting to place buildings like the recharge station on the ground results in the message "Must be placed on utility drone". It took a bit of experimenting where I tried to put it on my toolbelt drones and on the three drones I started with before I was able to put it on a foundation. The crafting system is pretty neat, but rather cluttered. It's mentioned the ESC menu has help, but I couldn't find anything of the sort (maybe it got removed?)
All in all, this seems really promising as a prototype and I'm eager to see what happens in the future (especially with things such as hacking, which as I understand isn't a thing yet)
