Bravo! Very good run. But why you didn't submit the 11.10 run?
I think in-game timers min minute is 4. For example, if you IGT is 3:26, make makes it 4:26. I don't why develepors made this if they did it. Only way to 100% prove this would be looking through the code. I don't think removing IGT would change anything. And if you remove it you should say IGT is buggy or something like that in rules.
Spiltting the leaderboard would be a good idea since vertically shortening wasn't possible in original web game. But like ChargedSquid said game isn't probably isn't popular enough. But if it is added making sub category (For example in Run, you can choose speed, chacter and version on main category) would be a good idea cause if new categories added like 100% spiltting them would be easier.
100% would be good but like ChargedSquid said there isn't any way to determine it. Since main collectables, octobearpus, doesn't show how much you need to or did collect. If 100% would be a thing we need to decide what is required (like collecting every octobearpus, talking to every npc etc.). And karma system makes it more complicated.
(btw thanks for making my run 4.54)
