Ahhhh yup! When I got to that point with Résumé, I basically set myself an end date and said "this is when I'm releasing this", which helped a lot. Do you have a list of what you wanna get done and what needs like, final-pass polish?
It's still hard to pinpoint how much time is left, as my time to work from day to day can greatly fluctuate, and I have trouble estimating how much time each thing will take me ^^;;
Yup, I have that same problem with my day-to-day schedule, haha. It's the curse of trying to sneak gamedev in between work and sleep :P Good luck! I'm psyched to play it :)
I largely suspect that I specifically overestimate how much time I actually need so that I can "surprise" myself with how "quickly" I get things done. Though, if things do end up getting done within the prescribed window (give or take a few days), I can still feel good, because I made an accurate prediction!
