Thank you sooo much for playing and leaving the feedback!
First we tried 60 sec timer, but for us it was very easy and always-a-win situation. Without much time for testing we quickly adjusted to 30 sec, but I assume since we memorized all attributes well then we've been able to win in most cases. It is true you need to be fast, as hesitations will cost a lot. But I agree either skeleton processing of questioning time should be adjusted.
Next time we will let other people play first and ask for feedback quicker.
