The game was actually supposed to be a creepier type of game where you climb down into this mountain and there are pitch black shadow hands in the walls that would grab your head if you got too close. But it ended up being a chill game which I am happy with!
For the caves I just used rudimentary shapes like cubes and extruded them along to make a path way then I loop cut and extruded it some more to make other path ways. I didn't want to make it too complex and have it be a serious maze but just a nice small, easier paced one. I then modeled around the maze that I had made using basic shapes. I didn't get a ton of time to texture paint so it does look awkward and bad in some areas (in my opinion) because time constraint. I then went around placing the mushrooms and crystals around which took forever, they have an emissive shader on them; they emit lights that was able to be baked into the environment and that was pretty much it. The caves didn't take me that long because after making the mountain which took me too long I had figured out an efficient way to do it. The mountain and the hole took me about 2 days or so while the caves took me 3 or so hours for modelling and texturing. Placing objects though took around 2-3 hours because there was so many objects and I had to make sure the lighting was okay by baking constantly.
Thank you for your feedback and i am glad you had fun!
