A lot of crypto/re challs were quite decent, but:
- We had a lot of troubles connecting to the challenges, everything was unstable.
- Late-stage surprises in PPC challs are not fun. Especially when you learn that there's another stage which different rules and now you need to rewrite your solver.
- Please don't make recon/ucucuga challs, there's no fun in solving them (at least if they take more than 10 minutes to solve). Even if you give them more fancy category names, like "OSINT" ;)
- This x86 code in the PDF didn't make any sense.
- Some challs looked like they weren't tested properly - e.g. in "MITM" challenge there was no MitM attack - my solver didn't even connect to the client hosted by the organizers. I just added missing flag decryption to the client provided by the organizers. Also, the memory corruption in the server in nonce incrementing was probably unintended :)
- Agents was quite weird, the biggest trouble there was parsing inconsistent server output (like sometimes using \n and sometimes \r\n) which spoiled the fun with easy but nice crypto part. And it was terribly unstable :(
- A lot of challenges were initially broken and needed later updates / hints.

Also, I really liked the scoreboard (nicely designed and functional), though the session timeout could be longer (I got logged out in the middle of the CTF) and the preset which challenges to show (e.g. only unsolved ones) was resetting randomly from time to time when navigating. Please fix this :)

There were only two pwnable challenges, and the quality of those two were very low Both of them were stack buffer overflows with obvious vulnerabilities, which is quite obsolete for a CTF in the year 2019. This CTF is the qualifier for an A&D CTF, so the proportion of pwnables should be the most prominent. However more than 50% were guessing. Very disappointing.

Forensic challenges were really cool! Hard for me, but i enjoyed to work with them, because the challenges were creatives, and not the usuals. Thanks, and go on!
