Thank you :-) It's difficult to remember to be honest because he was involved from very early on, when the game was barely playable. I remember showing him early prototypes and he used to give me "sympathy nods" because he didn't want to upset me, haha! It took (what felt like) months before the game was playable enough for him to enjoy it and by then he had already come up with many of the ideas and level designs himself.
