Beat a REAL level without dying once (1-1 doesn't count!).


You'll most likely get this without even trying. Just avoid getting hurt three times or coming in contact with pits/spikes/lava. Since you can't get this in 1-1, just play through 1-2 and be patient.

Beat a REAL level without getting hit (1-1 doesn't count!).


Just like the "Sprinkler" achievement, play through 1-2 while avoiding contact with all enemies.

Beat a REAL level without using the checkpoint (1-1 doesn't count!).


Checkpoints are the yellow signs that are found throughout each level. Either avoid coming in contact with one or turn them off by going into the menu in the hubworld.

Unlock the path to space.


You'll be able to go into space when you get the 16 water sprites from the first four worlds. These water sprites are obtained simply by completing each level normally (not the bonus levels or the ghost levels).

Beat the game. You'll know it when you see it.


To beat the game you need to obtain the 40 water sprites in the main 20 levels. Each level has 2 water sprites: one for clearing the level normally, and one for completing each level's bonus level.

Check out my Steam guide for all of the bonus level locations:

Collect all 'known' Water Sprites and Golden Diamonds.


Similar to the "Victory" achievement, except in addition to obtaining the 40 water sprites from the main 20 levels, you must also obtain the 2000 golden diamonds. Each of the main 20 levels has 100 diamonds to collect. They are not hard to find so you shouldn't have a problem collecting them. Once you have all of the diamonds and water sprites in the main world, you'll get the achievement and unlock Max's Grannie as a playable character.

Collect all of Grannie's medals.


When you unlock Max's Grannie (see the above achievement), you'll be able to access an additional 20 bonus levels in each of the main 20 levels. These levels are accessed by entering a door that can only be reached by Max's Grannie. The levels take some practice but are not that hard if you have checkpoints on.

Locations of the Grannie levels can be found in my bonus level guide that I mentioned above.

Collect 4000 Golden Diamonds, unnecessarily.


There are a total of 4000 Golden Diamonds in the game; 100 are found in each of the games 40 levels (20 regular and 20 ghost levels). No diamonds are found in the bonus levels. If you got the "Earned Your Allowance," your already halfway through getting this achievement.

These achievements involve levels in the ghost world. To gain access to the ghost world, simply go to the mirror on the stage select hub and press up.

Collect all the spooky Water Sprites.


To get all of the spooky water sprites, you just need to clear each of the ghost levels by collecting the water sprite at the end. There are no secret levels in the ghost world, so don't worry about those.

Unlock all characters.


In the ghost world, you can find various Renegade Kid developers to unlock as playable characters. They each play the same as Max's Grannie, and cannot be reached by Max (use Grannie or other Renegade Kid) . Here are their locations:

1. In level 1-1, jump and boost upwards next to your house.
2. In level 2-1, boost upwards and to the left when you reach the checkpoint.
3. In level 3-1, boost upwards and to the left when you reach the end of the mini tunnel you start in.
4. In level 4-4, keep boosting upwards at the start of the level.

I hope this guide served a purpose. I'd like to thank Renegade Kid for porting this fun 3DS over to Steam, as well as myself for making this guide. If you feel that this guide can be improved, please say so in the comments.
