Level 11 seems impossible, but there are discussions about level 13 and 15, so I am probably just extremely bad at this game. Any tips on how to get past level 11? It's the level that looks blue and has a blue key you can pick up during the level. Jeez, this game is annoying......

I am already finish the game and get the "GG" achievement but I also miss the "ERROR" and "INFO" achievement. How to get it?

and i think there is a bugs on level 10

I wish the devs upload a video with a walkthrough of this level, cause I don't believe it is possible to finish it right now.

I just bought the DLC, loaded my save file and completed the last level again but after that the game ends. Furthermore I didn't get the achievement for "DLC - Buy DLC".
