I'm sorry that you had trouble with the puzzles! Just to make sure, did you use the "objectives" menu as a guide? (Regarding the facility, placing only 2 fuses was a bug that was fixed in version 1.0.4!)
We've tested the puzzles and made improvements accordingly, but we realize that it's difficult to make this game perfect for every kind of player. We'll do our best to take note of everyone's comments and improve it based on that!
