This is an amazing game! It's very different from a typical minetest game. Expect to die frequently at first, but as you get to understand how things work, you'll be able to make it a few days before dying! :)
The weather is your biggest enemy. Find shelter and resources to build a fire and cloths so you can survive the first night. Next you'll need food and water or you'll discover what the second biggest cause of death in the game is. Exhaustion is a serious problem that'll leave you unable to move if you don't take time to rest. The most serious threat you'll find on the surface is the male duck which are very aggressive. Easy enough to avoid, but expect to add a few bodies to the graveyard looking for a quick meal.
I've progressed far enough that basic survival isn't my concern. I have plenty of clay pots and know how to get water from multiple sources. I've farmed most of the editable plants and learned how to make flour and mashed Anperla. Cooking is a challenge of it's own but once figured out, you're risk of death is greatly reduced. You could happily live out your days at this point; farming and living in caves.
Learning to make bricks changes everything! Being able to create blocks that don't fall, absorb water or erode make creating permenant structures possible. You can now build a home to live out your days in style! Next is the challenge of Iron smelting. That's where I'm at now. I have my first Iron Ingot , but am still trying to perfect the process. Can't wait to see where the game takes me once I enter the iron age! Do I finally get a pickaxe?
The game is well worth the effort. Frustrating at times, brutally unforgiving, and highly addictive! I haven't had this much fun since I first discovered Minecraft back before Notch sold it.
