I personally enjoyed learning more about the different languages that were used at each level. Granted I'd be meaning to try out node/scala/go in a more meaningful manner and the ctf problems were the perfect setting. The downside to this is that it can be difficult to learn a new language and solve the problem at hand.

I agree level4 was a bit undercooked and not as didactic as it could be. One could simply clear the level by using raft as a black box. Personally I enjoyed level 3 the most given the trade-offs that were present in solving it.
