Personally I had few lessons that may or may not help next time.
1.Decide how big you want to make the game (levels/mechanics/characters/etc) then commit to 1/3 of that
2.The more you plan the more itll make sense in the end
3. Start, and end, simple
4.Learn techniques before hand: Yes and No, I used this time to force me to learn a few things I've been putting off but at the same time I could have used the time adding to the game instead of learning how
5.Constuctive feed back equals gold/compliment feedback equals head pat
6.Dont follow any rule 100%, improvise strategically
