Hi! I'm the moderator for Repton (https://www.speedrun.com/repton1), which I added to the site yesterday. I don't expect this game to get much attention, but would like to populate it with my own records so that they are there for others to challenge :)
Level 11 (Giant clam) is a concern, because this level plays out completely differently depending on whether you accept losing a life, or complete it with one life. If you accept losing a life, you can do the lower half first, which lures the monsters into a safe place so they won't disturb you during the upper half. To illustrate how much difference that makes, my current best time for the level is 2:34 one life, 2:07 losing a life.
Obviously it would be nice to separate these two runs. However, for the majority of levels in the game, "1 life" doesn't make any sense as a category because best times will be done on one life anyway. So, is it possible to have an IL category for just this one level, or should I maybe add "Giant clam (1 life)" as a separate IL?
