Oh sweet, well not a ton of people, but it should give you a good feel for things. If you want to do another session it might be helpful to keep iterating until you get the gameplay where you want it.
I won't be available for many weekend tests this month. Probably only the weekend of the 15th/16th. But if you advertise another test early in the week, it can give people time to dl it and make sure it runs on their system properly first so they can join.
Make sure ppl post their feedback in the thread!
