Quick guide, as there were none, and I got stuck at the very beginning, and I figured I'd share as I went.

WASD controls direction.
Shift is sprint
Ctrl is sneak
left-click interacts
Mouse movement moves camera
Scroll wheel zooms in and out
Esc brings up menu.

First area: You are some kind of badger-like-thing, mother to other badgers. (From here on out, abbreviated BLT).

1. You will see you are surrounded by smaller BLTs. You are apparantly the mother BLT. Now, you may be tempted to eat the smaller BLTs, but you cannot. You are the mother BLT and you must care for them. They do just about what you do. Except for one...

2. The Dead BLT. Looking around, you will find what looks like a black-and-white dead BLT. There is nothing you can do. Move onto the next room.

3. The following room, you will find two things, an exit that contains a forcefield adverse to passage (hereon called the FAP) that you must turn back from for no apparant reason, and a Nondescript Organic Plant Edible. (Hereon out, called the NOPE).

4. At this point, you may be tempted to eat the NOPE by using the interact button. But you shall find you merely carry the NOPE. You may be tempted to drop the apparantly useless NOPE, but do not. NOPE, you will need it.

5. Go from whence you came, away from the FAP and into the room with the dead BLT.

6. Spoiler: The BLT is not dead, merely hungry. Dropping the NOPE in front of the dead BLT will will freshen him up. As he eats it instead of you, depriving you of NOPE.

7. Now, with your fresh BLT, the FAP is done, and you may pass, and explore the rest of the Grungy Earthen Den (GED). (Note, making a healthy BLT will be a reoccuring theme in this game. Watch the color of your BLTs to make sure they do not become a stale color. Staleness of a BLT can be addressed by fresh food.)

8. Having earned the right to the GED by properly addressing the FAP with your BLT, you may explore its volumous chambers. They are fairly linear except for one little round-about room. Branching off of it is a dead end and a path to the outside.

9. At this point, abandon your GED, it is useless to you. As you progress, you will see a cute little assistive picture (CLAP) will play.

10. As you first see the CLAP, it does not matter, for I have already given you the instructions before you got through your GED with your BLTs. As such, you do not care for the CLAP if it is not useful, because you should have figured it out some portions already to get where you are.

11. A third CLAP, however, will instruct you ram some wood with your shift. This is to add nutrition to your BLTs. This only applies to productive trees showing delicies (PTSD). In this case, it is a red fruit.

13. Now that you have gotten over the CLAP, deal with the PTSD appropriatedly, with direct forward aggression towards the wood. This will supply red fruit for your BLTs.

14. You will eventually encounter the CLAP again, as it demonstrates to you aggressively getting meat. It suggests hiding in the bush, but I find it is easier to openly chase when close and use the versitile left click. If successful, you now have an alternative to dealing with PTSD.

15. You will procceed, and having reached what you thought was the end of the CLAP, it will resurface. This time, use your BLT motherly instincts to protect your baby BLTs by Barking At Dogs. (This makes you a BAD Mother).

16. As you progress as a BAD Mother, eventually this will fall away, and you well have a meeting with an Aggressive Avian. (an AA meeting). The AA meeting after being a BAD Mother is unavoidable, so proceed with caution before you get in trouble and lose a BLT. Fortunately, you do not have to attend the AA Meeting with the CLAP, as you do not get the CLAP before an AA Meeting.

17. If you successfully pass the AA Meeting, you will be able to log off.

So ends this tutorial. Just remember the moral of the story. A BAD mother who gets the CLAP after abandoning her GED for a freash BLT will wind up in AA meetings.
