* Crackit 7 may be patchable, but my estimation is it would take far more work than doing it by other means. Btw, I passed the challenge without writing a single line of \"auxiliary\" code. I don't know if this is intentional.
* The PHP challenges are logical and (relatively) easily solvable, except for 5 and 8. Both rely too much on guessing, I think. But I haven't done them yet, so I could change my mind (but don't count on that). In particular, PHP 8 is very strange. I found the first password in no time, but the second one avoids me. And it encourages bruteforcing, which is not very educational...
* On the other side, I really liked the crackits and the cryptos (albeit some of them are repetitive and rely on similar themes). I'm having some fun with Crackit 12, very neat. And PHP 7 is quite elegant and a fine idea (you have to be *really* observant, that's a hint!).
* All in all, I think it's a good work from theblacksheep & erik.
It can be improved, as many of the challenges are not original, but it's going in the right direction. Now how about some Logic challenges?
