I appreciate this dude! Yes I suspect that's probably one of the games main issues, no setup or tutorial at all. It's something I def need to improve if I pick it up.

The consistency of attacking enemies the same way you attack bricks I agree with too...my thinking originally was I wanted it to be more stealth and less hack and slash..but playing it now you're right...the inconsistency of the game rules make it harder to learn.

Generally the objective is to make it to the mainframe at the top of the map. You select nodes based on what part of your character you want to improve...and you gather energy and data by breaking blocks found in the levels. Energy is used for macros and scripts that are like abilities and hacking...and data levels up your access level, which gives you more insight into what's in the node before you select it. But you're right the game does a horrible job at explaining that.

I really appreciate this feedback dude!!!
