Haha, true. I was actually even contemplating on doing a level where you'd need to alter the save or at least check the sources or something like that. But might have been a bit much for most people. I think even the current challenges are too tough. What parts did you find the most frustrating ones?
i believe i had an impossible maze... assuming there were definite go / no-go keys, rather than sequences that would change the behavior of certain keys.
I'm also just no good at the "spinner" level, though i believe skipping that may have screwed up the following part a bit... the questions didn't seem to display, i ended up getting through it by key mashing lol, after which Antonin very quickly pressed a bunch of number keys before moving on. Also, the keys for GERMANY were highlighted throughout the quick typing section, despite that not being the answer...
The maze is the same no matter the keys. But yeah, it's not too fun of a concept for sure as it's basically just trial and error with a bit of a memory requirement. And from that description yeah, seems like you managed to break something. Just incrementing the level shouldn't be enough but maybe in conjunction with something else you did or something. Cause it seems like quite a few of the games weren't working 100% correctly. Like I guess Germany was the solution of a round but the keys didn't get reset properly for some reason.
playing through again to check out what i missed and had the same issue with the questions... maybe it's a joke i'm not getting. but i did see a few new games I had missed! maybe my fiddling messed up more than I thought! now I'm stuck at the "related keys" puzzle, can't seem to figure out how to end it...
