Like the previous Tesla game this was also very fun, it is good that you pulled off going with a different style while keeping to the same overall aesthetic. I personally preferred this one more than the last in gameplay style. Even though it was pretty much impossible to loose once using the full doctor talents and having 2 of them in the team, but alas I didn't care much for difficulty compared to the fun it provided instead.
Story wise, I enjoyed the way you handled it with having Stalin being friends and having Edison giving pretty much stock evil villain lines which for such a small screen time did make him fun.
Worth playing until the end and perhaps replaying one day with it being short also.
