I have been working on several mini-challenges that will be used in a much larger game. (all done in Construct 2 with a little bit of server side).
I have another one done. This one is a slot machine type of game (mixed with a little poker).
Again I was hoping to have a few plays to get an average score. I could then use that data to set the "Pass/Fail" marks for this mini-challenge.
It takes about 5 minutes to play (at the most).
It will save your score automatically.
