I don't understand...
I don't understand how people are getting confused by this? I love this game, it's great, it adds a kind of adventure/quick paced puzzle to NG, and I like that.
I think critical information like "don't touch the block twice or you lose" should be displayed on the first level, not on the second. And speaking of which, why in the hell do you lose if you touch the block twice? I thought you could go back to a red block and turn it back to good block but no, you make one mistake and its game over.
You are killing the game at the very first levels. Level 1 was hard because you didn't get enough information about the game. Level 2 is hard because of the game rules. You want people to play your game, don't you? I like a challenge but damn dude, relax a bit in the first few levels at least :P.
All instructions are in the comments, as well as in the game. If your struggling look at the walkthrough: http://www.youtube.com/watch?v=7wB86x LkBAM
The name is wrong! But..
... The game is clever. I played the first levels, and I liked how does it work. It's a bit different form the other games, and I like it.
The graphics is really good, like the effects.
Now, speak about the name. The game's name is wrong, because I think that you wanted to make it mean "Arc of light". Since from "of light" specificates the material that is made of, the name should be "Ex luce arx", not lux arx, since from "lux" it's not an adjective.
Actually I was going for "Light Tower", I don't know latin so I just chucked it into a translator! Oh well thanks for pointing that out
Addicting and hard
i like it but its a little to hard
