Hi Mark, I really enjoyed this creative exercise. Although when you came to your conclusion, I felt like the one thing I noticed as an observer wasn't on your list. Since I appreciated your experiment, I figured I'd share it.

One idea leads to the next. Frustration from the 1st and 2nd games led to the 3rd game being a literal expression of that frustration. You then distilled that frustration further into a simple idea you could easily execute and refine well within the time parameters. The process started to inform the work. You reached your apex (imho) with Voice Invaders, which applied a fun concept to a solid, simple mechanic you'd discovered genuinely.

If I had to guess, I'd say you took a food break here, because the next few games seem like you're digging in different holes - each of which could be a great starting point (like Pecha Kucha was). If I had to distill this epic comment, I'd say your whole process created 1 really solid game idea in the middle - so another lesson might be in recognizing that first ideas always need to be broken, twisted, abandoned and ultimately screamed at until finally you're looking at something worth polishing up and sharing.

There's two cents from a total stranger - thanks for sharing this - I really got a lot of insight from watching it. Thank you.
