I would like to suggest adding IL leaderboards for both Easy and Normal. In some levels we'll be able to grind for strats that we wouldn't do in a full-game runs, and as a nice side-effect it would document the actual up-to-date fastest way to do every single level.
I'm not sure about using IGT (because it's less precise than RTA, and idk if it can be abused by pausing). But I would still record it as a second variable. Btw there's an google sheets document with some IGT times tracked into it. So I think it's safe to say there's an interest :) https://docs.google.com/spreadsheets/d/1tC36y0wTov708RAhEC1EMhao_MhnjKxpx9mcihpc_HM/edit#gid=1572477398
Bump? And yes of course this would be RTA, not IGT. There's also the extra hearts, I wouldn't consider an IL run valid if it took more damage than would be possible starting at 2 hearts.
