Still refactoring/expending the ability system, as I'm trying to add some challenging cases that play well with the other abstractions. Being sick for several days certainly did not help. Managed to add two example skills, a variation of "Charge" that can target a wall tile and breaks it, and a variation of the Lasso skill which can select an object or a creature and hurls it towards another object/creature/tile, which can cause some knockback as well. This involved some bug-fixing in the animation order/delay system, and the creation of a shader that renders a bezier-powered lasso for the hurling animation. I'm quite happy with how it looks overall.
