Thank you!
I got to say on the latter, I tend to over aim with the amount of work, and then end up cutting things off, and hopefully ending with a level of completeness. So I got to say, be ready to constantly think of what features you want to prioritize and evaluate what you can add realistically, as one thing that almost didn't make it in was dismantling defences (partly because I forgot to add it for a quite while), as I added it about 2 h before deadline.
