Normally the review commiittee takes about 3 to 4 months to review the entries, so it's recommended to keep the original 7DRL version at least for that long.
I also have browser game and I created a launching screen where you can decide to launch a version with critical bug fixes, the original submitted version (including bugs) or an updated version beyond 7DRL
OK, follow-up question. I've marked my submission as "incomplete" even though it's playable, because it's missing a lot from my original goals. Do "incomplete" entries get reviews, or only "success"es?
