I have always liked the idea of button up in games and I feel like we don't use it enough. We always use the button down to register a button press.
button up has always been a concept that I would like to use. It would force the player to consider when to let go of a button. There are only so many buttons someone can press at the same time. Think about climbing for example and how you need to use the same limb (arms or legs) to move into the next stop. You can't let go of a spot we are hanging on just because we are interacting with it.
I always loved the idea of magic summoning. Using different spells at the same time to summon something. I think Magica did it well by reusing the idea from Dota2 Invoker. The problem is usually having to memorize all the combinations
I think the spells need to be a button press. so you can shoot a fire ball, or ice ball or such
BUT
if you press two button and hold both and let go of both, then you get the combination of the two
maybe alchamy of some sort to use this.
