when we started the game, we knew for a fact that we would have to support mouse and keyboard. And, then we would also have to support, um, touch devices. Um, we then made a deal with - well, there - well, what happened was like, I don't want to get into specifics here. But, we had to support the clam shell experience, which is, uh, those laptops that have touch, um, mouse and keyboard support, and also you can plug in a controller with USB. And, they all have to work seamlessly. In fact, you can play the game this way, with multiple people playing it. Like, on touch and mouse, like, all three will - like, the game should seamlessly switch between all of them. Um, and not interfere with the experience, which maybe a lot of people don't know, is that you can. I mean, adventure games, a lot of them, are played with, like, you know, you sit down with someone else. And, it's fun. Like, you're experiencing a story. You're kind of both figuring out the puzzles. Uh, and we want to support that. But, we didn't realize that we - and, then - and, then of course, we also ship for [14:35:40 unintelligible], which is controller only. And, so we had to come up with a - a controller scheme. And, the thing is that, in the beginning, there are some interfaces that we designed, that, um, are not ideal for a controller. And, like, we had to go back and like, really - I mean, with every - with every new interface, and there are a lot of new - new things in Act II, uh, whenever we had to design, I remember, like, it was like, what if we do this? What if we - what if this is how it was controlled? It was like, no, they can't - that won't work, because, you know, what if it's - it's on touch, you don't see a cursor. With a controller, it's really awkward to hold down a button while doing something else. You know, while dragging the stick. Um, so we - the entire time we were designing the puzzles, we actually had to keep in mind, okay, like, on this, is it okay - the house is going to control? Okay, that will work, that will work. What about on the touch device where there's no cursor? Okay, that will work? What about on the controller? Like, what's really annoying and hard to do there. Because, we didn't want to, um, we didn't want to do anything that would be like, inferior experience with any of those input devices.
