Retro-Pixel Castles is a very brutal game if you don't play your cards right, this guide is designed to get you up and running. It's not all inclusive, but it'll get your village to a sustainable state!
The first few days of Retro-Pixel Castles can be daunting, but the first one is probably the most critical. You will find yourself with absolutely no buildings, and you'll have to setup shop quickly. You will first need to find a place to place your Village Center.
Placing your Village Center is simple, just click on the dropdown on the top GUI over on the right hand, and select a place you'd like to drop it. Look for a place with food, trees, rocks and crystals! You'll want to be near all of these in the future.
Now that you've placed your village center, you can assign villagers to it, by clicking the + and - buttons on the GUI. (TIP: You can quick-assign all available villagers by right clicking on +.)
Once your villagers are assigned, you simply need to select resources to collect. The village center requires both wood and rocks, select the assign work buttons for them on the left hand GUI and select some resources you'd like to gather. As soon as they are selected, your workers will head over and start the process!
(NOTE: Once the Village Center is complete, your villagers may decide they want to repair any abandoned buildings in the area if you're near any. In most cases, it's probably a good idea to let them complete those buildings first, but some may require additional resources you don't have access to. If you want to stop them, you can pause construction by clicking on the building and hitting the pause button.)
Once your Village Center is completed, you should probably build housing. You can select housing on the right hand GUI. You won't have the correct materials yet to build anything other than a few tents, so go ahead and place a few down. The builders will then go collect the resources needed and put them together for you!
Next, you'll need a farm to feed yourself. Back on the right hand GUI click on "Farms" and select a farm you'd like to build. You can build either of the two current options at this time, so pick whatever you want.
Now that you have farms built, you can start harvesting food. But you need workers assigned first, so be sure to unassign some workers from your Village Center, and then click on the farm and assign them there. Once assigned, you can click on the Assign Work (Food) button on the left GUI and select some food on the map for your farmers to go collect.
Finally, you should probably build yourself a Guard Outpost and assign a few guards to it. You'll need these guys to defend your villagers while you work. Like the farms and housing, you can find the guard buildings on the right GUI. Just click "Defense".
That's it! You're on your own now. You'll probably want to build yourself a Lumber Shack and Stone Shack next, get a Crystillery running and maybe get some magic buildings going. But I'll leave you to figure out the rest.
