So after playing only a few hours with my buddy, we really enjoyed the data block assembly. It quickly made sense and became an enjoyable puzzle. It was a compelling system and something we want to delve deeper into.
The unlocks made the EXMs a lot less daunting as well.
I do recognize it is somewhat complicated however. Maybe a tutorial that explains exactly how to make the shapes match up properly would go a long way to make the system clearer.
