Besides planning chains and setting them up, the most energy-consuming thing about playing VS falling block puzzle games for me is splitting my attention into the main board where the blocks fall, and the preview block in the upper part to plan where to place the next set of blocks. Maybe I'm just slow, but I notice my gf just doesn't need to even put that much energy into it and she just naturally wipes the floor with me effortlessly. Just to be able to play decently and stay more or less tied with her i have to get into super tryhard mode, get super concentrated looking at both the upper part and the main board, and once blocks start falling faster, and giving me less reaction time, I start twitching my thumbs on the controller like crazy. Let's say I'm not proud of the amount of effort I need to put in order to just keep up with her.
I want to justify it by thinking that women are just natrually better at these games.
