Sounds good. Yeah running out of time is always the key, it's the reason most of my jam submissions suck pretty bad.
Lately I've tried the 1/3rd rule. I consider how long I have to make a game, then divide that into 1/3rd. I assum it's going to take twice as long as I thought, so that's 2/3rds of the alloted time. The remaining 1/3rd I keep as buffer time for playtesting, bug fixes, and polish.
But yeah looking forward to seeing your pro-jam fixes and seeing what you make for the next jam as well.
