I just bought the season upgrade for SBCG4AP yesterday and found that Math Kickers in episode 2 is hard to play with a german keyboard since the keys for 'z' and 'y' are swapped compared to a US layout.
While I doubt this will be fixed for this episode, I thought it might be something you might want to consider for further titles - I guess it should be possible to figure out the actual keyboard layout from within windows and configure the game accordingly. Alternatively, one could try to avoid keys that are in different positions on different layouts - though I don't know how many layouts are out there and thus whether this is feasible - or, at least in the case of a german keyboard and those letters, make both keys work identically.
Any feedback on this issue would be greatly appreciated.
And, by the way, thanks for some very nice games to all the folks at Telltale!
