Let's forget about WHDLoad trainers - if I need trainer, I will sort them any which way or do without them or not play the game. It's more about the tempo of the game.
Chill tempo. Do this, go there, open that, pick it up, go there, unlock this...
Or infinite "rotate/sort/stack" puzzle games without the game ended from too increased tempo.
Just a way to clear thoughts while twiddling thumbs.
Opposite of "QUICK! Duck under the spikes and shoot 5 enemies in 1 second!" or "You spawned, you will be punished... we are sending 10 homing AI towards you... shoot or die"
