Niceeee. The cork would likely pass as an unnoticed hack in a GM event.
This is a typical "with power comes responsibility" situation, Jisse, so make sure you use this new set of skills wisely ;)

About the objects hacking, awesome that you remembered doing that. It's something that's definitely still on my to-do list.

The best advice I could give you on it is: when you have such a great idea like that, explore it to it's fullest before you release the concept to the public.
If you had made a cool intricate replay around objects hacking with spheres like those it would have been a massive hit. Now people are already aware that something like that can be done, so they'll expect it and be a lot less surprised.

When you get to these elite levels of replay-making you need to think about details like that and not just the replay itself since it can make the difference between a really cool replay and a replay that goes on the default folder for being a landmark.
