I think it was the one with the clock and one of the others, they just didnt seem to have any effect, but maybe it just wasnt noticable enough

The clock one may have been a bit confusing, and would probably have required a tutorial. You need to hold down the right mousebutton for an effect. The teleportation ability may also have been confusing, as you can only teleport to valid places, which means places not too close to a wall nor enemies.
