Late understanding of lack of time for this hackaton and desire to overcommit to different projects.
I've just realized I'm not ready to spend nightless nights and effort for this hackathon :(. Perhaps it can be foreseen, but I'm not sure. I wonder how many characters this text field requires? Is it several hundreds? Maybe it's a half of a thousand? Who knows... Perhaps I will know. Alright, now it's ok.
I've opened the main docs page of MUD, browsed to the quick start. Also i've tried to think in general, is it a really useful tool or not? It seems that at some point, when you have highly specialized project, you need to develop your framework, that's why it feels wierd to use MUD when it's possible to use plain solidity.
