If you would like a leaderboard for a specific level, please request it here. Levels that have consistent timing or are not sufficiently skill-dependent will be denied.
(Edit: replaced "difficult" with "skill-dependent" to add clarity for purely luck-dependent stages)
Unfortunately, that looks entirely luck-dependent and not skill-dependent. The optimal IL time would happen if the star chest spawned two rows under the player and the player could hold straight down to clear the path without encountering any walls. That could happen (I checked the source code) so anyone could do it if they wanted to reset enough times that they got it. The time couldn't be improved beyond that, and that's not really worth a leaderboard.
To prove my point, here's an almost-optimal completion that I got after a bit of resetting, and it took no practice-based skill:
If you find a way to make that stage skill-dependent, I'm willing to create a category. I know that navigating the caves with monsters running around would take some skill, so I don't want to rule out having something fun for this level - I just don't see a plain IL as a good category here.
I've corrected my wording at the top post to remove the ambiguous "difficult", so thanks for pointing this level out :)
