Getting 100% in Minicraft isn’t too complicated - you’ll unlock most of these just by playing the game naturally and upgrading your gear. But a few require going out of your way.

Here’s a somewhat readable “walkthrough” to grab the standard achievements in a “single run”.
In the title screen, go to “About” menu and input the Konami Code: Up, Up, Down, Down, Left, Right, Left, Right, Menu, Attack (aka square, cross) (Nice Try). Once done, start a new or load back into your world.
Punch the nearest tree until it drops wood and pick it up (Wood!).
Sometimes trees drop acorns. Pick one up and plant it in dirt or grass (Green Thumb).
If you see an apple drop from a tree, take damage to lose some health and then eat it (An Apple a Day, Hungry?).
Find a flower and plant it on grass (Botanist).
Open your inventory, equip the workbench, and place it on the ground (Getting Crafty).
Open your inventory, equip the Power Glove, and use it on the workbench and re-place it (Power Within).
Use the workbench to craft a wooden pickaxe, wooden axe, wooden sword, wooden shovel, and a wooden hoe (Getting Started, Lumberjack, En Garde!, Digging Dirt).
Equip the wooden hoe and use it on grass tiles to get some seeds. Plant those seeds in the dirt so the wheat can grow while we continue.
Equip your wooden pickaxe and look around for some exposed gray rock. Mine a piece of stone (Rockin’ It).
With some stone in your inventory, go back to your workbench and craft the stone pickaxe, stone axe, stone sword, and stone shovel (Stone Age, Stone Chopper, Stone Warrior, Stone Digger).
Continue mining regular gray rock. There’s a chance coal will be dropped, pick it up (Smudged).
Now that you have stone and coal, craft a furnace at your workbench and place it down (Smelting).
With the wood and coal you’ve gathered, craft a torch at the workbench. Place it on the ground (Let There Be Light) - (I’d also recommend crafting a few more of these for the underground).
Before doing anything else, save your progress! Open the pause menu, select “Save & Quit”, and then reload your save. This manually saves the game so your progress is not lost for the next step.
Now drown, walk on lava, walk into a cactus repeatedly, or let a slime or zombie kill you (Respawned).
Once you respawn, run into water and swim until your stamina drains completely and you take at least one point of damage (under the water). You don’t actually have to die.
steps 16 and 17 can actually be combined :)
Kill a regular green slime (Slime Slayer) and pick up the slime balls it drops (Ew, Gross).
Find a zombie and kill it (Zombie Killer) and grab the cloth it drops (Soft).
Look for a staircase to go down to the first cave level. Step on it and go down (Going Under).
Look for spiky, gem-like structures with brownish-red coloring. Mine them for iron ore (Going Deeper).
Take your iron ore and coal back up to your furnace. Smelt iron bars. Use the iron bars at your workbench to craft an anvil, and place it down (On the Anvil).
Use the anvil to craft your iron pickaxe, iron axe, iron sword, and iron shovel (Iron Will, Iron Woodsman, Knight’s Blade, Hard Labor).
Craft an oven and place it down (Heating Up).
Use the oven to melt some sand into glass. Then, use the glass, wood, and slime at your workbench to craft a Lantern (AHH, MY EYES).
Check on the seeds you planted earlier and harvest the grown wheat. Use the oven to bake some bread (Baker). Note: I’d recommend baking at least 10 bread so you have enough healing for the Air Wizzard boss!
Craft a chest and place it down (Pack Rat).
With your iron pickaxe, go back to the first cave level and search for a downstairs ladder to reach the lower caves (Deeper Darkness).
Find spiky, gem-like structures with yellow coloring. Mine them for gold ore (Shiny!).
Take the gold back to your furnace, smelt it, and use your anvil to craft a gold pickaxe, gold axe, gold sword, and gold shovel (Golden Touch, Going for Gold, All That Glitters, Gilded Spade).
Head back to the lower caves with your gold pickaxe and find the stairs leading down to the dungeon level (Into the Deep).
Find spiky, gem-like structures with purpleish coloring. Mine them to get a gem (Deep Find).
Take the gems back to your anvil to craft the final tier of tools: the gem pickaxe, gem axe, gem sword, and gem shovel (Best Pick, Final Cut, Excalibur, Six Feet Deep).
Look around the overworld for a snow biome. Inside the snow biome, find and kill a cold slime (Frostbite) and a cold zombie (Frozen Dead).
While in the snow biome, use your shovel to gather snow, and then throw a snowball (Snowball fight!).
Assuming you already killed the regular versions, this will complete your hunting checklist (Monster Hunter).
Note on cold mobs & snowballs: If your current world didn’t generate a snow biome, you won’t be able to find the cold variants or craft snowballs. Just continue with the guide and beat the game. When you roll a New Game, explore to make sure it has a snow biome before hunting them.
Now explore the surface to find the sky stairs. They are surrounded by a barrier of hard rock. You will need your new gem pickaxe to break through the rock. Climb the stairs to the sky level (Sky High).
Explore the clouds until you find a Cactus, which looks similar to the spiky gem structures you mined earlier but in white. Use your pickaxe to harvest it. (NOTE: Alternatively, if you found a cactus in a desert on the surface, you can just place it on a cloud tile and break it) (Prickly Up Here).
Explore the clouds until you find the Air Wizard. Defeat him to beat the game (Air Apparent).
When the credits start rolling, watch them (or skip them by pressing and holding any button) and after, choose to keep playing (One More Turn…).
Pause+Quit - From the title screen, choose “Start game” to overwrite your save and start a New Game (Back for More).
For true 100% completion there are also the two QR code achievements that can be triggered in the main menu by pressing:LTRIG+TRIG+UP and LTRIG+RTRIG+DOWN.
