best map for achievement XD

Nice to hear, I did not think that this game is very well known.

I've actually played that, and it is definitely my favorite 3d web game, and it would be my 2nd favorite web game if it wasn't so short

Maybe this small game is inspiring you for further levels:

Make sure you match the color of the clue to the color of the carved block above the column

I tried these combinations:

But it didn't work. Am I missing something?

Very cool level, I figured it out pretty fast.
Had to do some head scratching first though haha

BTW I am using the idea of using platforms for the wrong ones and having the sounds be clues in my next level, "Action".

If it still doesn't work, screenshot your current answer so I can see what you might have done.

Mine works perfectly fine. Make sure you're not looking at the floor one upside down. (The correct way is standing at the entry.)

I tried it but it didn't work. Any chance you could check it? I double checked the info you hinted and think I got it right, but it didn't work. :(

Hm ... subtle! Ok, I'll give it another try!

It's not a guessing game. There is a clue in the level. Hint: Although the level is world 2 themed, I have (more than just) decorated using blocks from worlds 1, 4, and 3

If you just want to keep it a guessing game, here's how the math works (when only one surface of a cube is visible):
There are 12 key cubes to choose from for the first energy cube - place one.
There are 11 remaining key cubes available - place an energy cube.
There are 10 remaining key cubes for the last energy cube.

You multiply 12 x 11 x 10 = 1320 to get the number of possible combinations.

With a 3 cube door, you have 3 energy cubes and 3 key cubes. Place an energy cube.
There are 2 key cubes left; place a cube.
There is one key left; place the last cube.

You multiply 3 x 2 x 1 = 6 to get the number of possible combinations that will open the door.
Happy math! :)

Your probability of solving the code is therefore 6:1320 or 1:220. Another idea is to remove the müßig so you can hear the door locks activating, as long as the other doors are out of range - or use platforms for the other activation cubes. Just some ideas. :)

I tried the level; you might want to know that there are 1320 unique combinations, 6 of which will open the door. So ... I didn't finish the level. You might consider allowing the player to peek at the front of the door somehow, or at least at 2 of the keys on the front of the door.
Unique, though, to have the door turned sideways - I really like that! Unusual and creative. I liked the first blue block placement too, and I really liked the way you built the cover to hide the doorway. :)
