A small, but very nice CTF.

Good things:
- 3 hardware challenges! Including a side-channel one, with oscilloscopes available to players. That's really rare on CTFs.
- Diverse challenges, with (IMO) good balance between categories.
- Stockholm is a very nice city :)
- Food and drinks provided during the CTF.
- Flights + hotel also provided.
- Helpful and friendly organizers.

Not-so-good things:
- Some challenges had unintended solutions, which made them *much* easier and allowed to circumvent the whole problem (e.g. leaking a flag from env in a crypto challenge).
- icanhazfile (a web challenge) was a bit guessy in our opinion.
- There should be a break for the night during the CTF, so we could take some sleep and a shower. Staying ~28h in the CTF area without those two isn't a nice experience ;)
- The hotel provided by the organizers was in the middle of nowhere, so we ended up with renting something in the city on our own.
- The before-CTF party was quite hard to find, and it wasn't possible to buy drinks, only beer :(

Anyway, good luck with the next edition and hopefully cu there! :)
