That sucks aye, I know how you feel Id been testing in the editor and standalone just to have some bugs pop up only in packaged build. I think I got a good tutorial or two out of it and Im certainly looking forward to a proper release where I can spend some time on the mechanics I had to drop because of time constraints, Im certainly looking forward to the post mortems done by the devs bout their projects, I did suggest to our team that we each do them to pass on some of the experience.
As this was my first ever Game Jam and being extremely reluctant at first I finally found the motivation and Im surprised how much I actually enjoyed it
