A simple base-building game demo made for a C++ independent school project with Libtcod. The gameplay aims to be a super bare-bones demo imitation of the playstyle of games like Oxygen Not Included and Dwarf Fortress, and the name comes from the the Derinkuyu underground city site in Turkiye.
WARNING - On my Fedora Linux system, the program sometimes randomly crashes on startup. You may need to attempt to launch the program several times until it starts successfully. I'm still new to C++; not sure why this is happening.
The goal is to raise the "morale" of your three characters ('@' symbols) by building them basic amenities like shelter, beds, and a stockpile of bread. After morale passes 6 (all three characters have bread and a bed) the object shifts to selling as much bronze, flour, and gems to the trader for points before the timer runs out.
WASD - move cursor
Space - move villager to tile; rapidly use on multiple tiles to force everyone to move
Backspace - erase queued jobs; use this if something appears to be buggy
Q - chop trees
E (click once, designate a rectangle with WASD, and click E again to confirm) - dig tiles
I / O / P - plow soil, plant grain, and harvest plants, respectively; uses the same double press rectangle designation as digging
R - use smelter (copper (x2) and tin (x1) to bronze), millstone (grain to flour), or oven (flour to bread)
Z / X / C - Z and C scroll the build menu at the bottom of the screen and X orders construction of that item on the cursor's tile. Buildings require wood and oven / millstone / smelter need stone. When hovering over the trader ('&' character) with the cursor, these three keys instead navigate the trading menu.
