About this game

Embark on a subterranean odyssey in Going Deeper! : Colony Sim, a challenging offline colony management game, set in a rich fantasy world. Delve into a six-layered world, from the surface to five distinct underground levels, each teeming with valuable resources and escalating dangers. Expand your colony, manage your resources, and defend against hostile goblin hordes in this immersive simulation experience.

Every unit in your colony is a unique individual with their own needs, skills, and quirks. Nurture their talents, equip them with meticulously crafted armor and weapons, and form specialized combat squads to repel goblin attacks. Will you prioritize skilled warriors, expert craftsmen, or a balanced approach? The survival of your colony rests on your decisions.

Tunnel deeper and deeper, unlocking access to richer resources but also exposing yourself to greater threats. Strategic planning is crucial: the resources you initially choose for your expedition will shape your entire campaign. Optimize your crafting and building processes to maximize efficiency and ensure your colony thrives.

Trade with a visiting merchant every two years for unique and valuable items you can't craft yourself. Choose wisely, as every trade-off could be crucial to your long-term survival.

Going Deeper! offers three distinct game modes to suit your playstyle:

* Campaign: Complete challenging missions and conquer the depths.
* Survival: Test your mettle and see how long you can survive against the odds.
* Sandbox: Customize your world and play with unlimited possibilities, tailoring the experience to your preferences.

Dive into the depths and build your ultimate underground empire!

This is for others who are attempting this game and have already (haven't gone deeper), the tutorial is short and does not explain a lot. 1. The pictures aren't the best representation of how to build your home. 2. The waves of enemy attacks don't have to be fought, after setting up food and a basic area, while building a foundation of a society start using a bit of wood or stone (whatever is in excess) for a wall to slowly claim territory. 3. (To the dev) make a more indepth manual/tutorial.

It's alright. Major downsides are pretty much everything. It's extremely difficult to really do anything. Good premise but it's just not fun to play due to, well, everything. If it was made a bit easier, have it so their happiness and food interest didn't drop so quickly, and things aren't so expensive to make it would probably be a bit more playable in my opinion. Also the stuff you can pick at the very beginning before you start is very slim and you don't have enough money to get anything.

Really liked the concept. But I couldn't find myself playing for more than a few tries before giving up. Game was a little too difficult, after just a couple years a goblin raid would just come in and knock everyone in the colony out, would like a difficulty option. Second, the npcs are just dumb, like how npcs in the military apparently can't feed themselves, even if they're starving. If the game was a little easier and the AI was a little smarter, I would see myself retrying this game.
