There will be a few posts coming up very soon, but I can go over these real quick
Areas of Feedback: We've disabled the areas of the game that aren't ready for feedback, so anything that is in the current build is fair game. Can you make games that you enjoy and would want to share? Are there things that work counter-intuitive to what you'd expect. Oh, and bugs...any and all bugs we want to snuff out ASAP.
Oh, and we'll be posting a running change-log of things we've fixed for the next update, so feel free to look through that before posting. Or post anyways - as long as you don't mind a quick "Known issue, we're on it." response
Release Window: I don't know how final the schedule is, so this one is a 'No Comment' from me. I'll keep you posted as these things are made official.
Sample Games: There are 3 included sample games and another handful in "The Arcade" (the online library of uploaded content). Should give you a good ideas of some of the possibilities.
Theme Weeks / Mini-Game Jams: Love this idea. Gonna steal it
This Alpha cycle is all about getting the game to a fun/polished point where it's ready for a wider audience. It still has some pretty rough edges, so getting those smoothed out is our top priority.
Can't wait to get your feedback, Silver!
