Really impressive event!

Regarding the platform's OAuth, we already made a feature request to GitHub asking them to allow for more granularity in scopes: https://github.community/t/feature-request-increased-granularity-in-oauth-scopes/116230

We make a promise here not to use GitHub again if this issue is not solved before the next edition. Despite the application being completely open source and running client-side, we understand that most teams don't have the time to audit it and that creating a new GitHub account for playing the CTF may be inconvenient.

However, we would like to hear about your opinion on the platform besides the OAuth issue. Did you like the platform? Do you have other suggestions so that you could improve it? Did you find it lame and think we should go to ctfd even if the OAuth issue is resolved? Please let us know.

Really loved the CTF!
The client side challenge based idea of hosting was very cool. Glad to have something different than ctfd.

1. CTFd sucks in general, and in particular after this https://github.com/CTFd/CTFd/pull/1300 I feel like it's better to use some alternative, because it's clear the maintainers are not interested in CTF-scene. I won't be surprised in they make it impossible to use CTFd without majorleaguecyber (it's already strongly connected) and then make majorleaguecyber paid with subscription fee...
2. This github shenaningans also suck. In fact the team I was playing with had a single person who managed to setup the flag-submission (from a brand-new github account). I personally was just using the fact that tasks were visible without "logging-in". It seems like lots of effort for absolutely no gain.

Thanks for the feedback Pharisaeus. ELT will work to provide a better experience for the players at the next Pwn2Win CTF edition!
