Excellent, forces you to really think by yourself sometimes!

Some of the logic (starting at level 2) was similar to Ouverture Facile (http://www.ouverture-facile.com/start/index.html for the english version) which I encourage anyone to try if you like these riddles!

Looking for more!

Made it all the way through! Really fun, please make more levels!

Thanks! I'm glad you liked it. Already working on new puzzles...

That was fun! Look forward to more...

PS: I went down a rabbit hole on @. Then I felt silly.

I cheated on 11. What is the thing I was supposed to figure out?

Here's a hint (SPOILER, obviously): https://gist.github.com/sharkdp/47f62f3fe6870c51b510cc912960...

Man, I'm just really bad at git.

I get to level 005, but was to lazy to do a script :P

What would be the logic of the script ? I didn't get it .. :/

I'm noob, what's level 2??

++ is the increment operator from C-style languages.

level007. I'm absolutely clueless.

Cheated. Tried to solve this for about 4 hours. Now I feel like a complete idiot... Still fun though! Waiting for new stuff!
