How do you gauge things like this? I mean, does coding the interpreter or items in the game count as level creation? What about prototype levels? We each made at least 5 testing levels to see how they worked and started that about 5 days ago.

Play testing with other people only occurred sporadically for the last few days of development. Getting feedback from sites like Hacker News is a kind of play testing. I'm still tweaking.

Programming is the big one of course. Unfortunately I can't really say how long I spent on it as it intermingles with things like level design and graphics. The levels themselves have a lot of custom code - I wasn't about to make a real level editor for such a short game. And, this being flixel, I wasn't using the Flash IDE to create this. It's mostly code, so I guess almost all the time not drawing, level editing, or making sounds was spent coding.

I got a buddy to make the music, but I made the sounds as they were needed using a synth :) I might have spent 2 hours tops.
