There are so many details I just adore in this game.. The shadow tentacle especially. That could not have been easy to animate. The tiny camera shake? The springy tweening? The hook motion? All of these come together to make such a powerful effect. Also.. the procedural fog in the foreground? Man, that's cool.
Thanks! I made the shadow tentacle, it uses a Bezier curve with randomized middle anchor positions, and spawns 20 particle effect instances along the curve to make the effect. That way, only the anchors themselves need to be moved for the attack via scripting. Arthur made most of the other effects like the fog and screen shake.
