Thanks! appreciate it a lot.
I thought the same, but for this game, it seems to mostly concern "Arcade mode run" and "Adventure mode run".
And I also went to the length of creating a discussion purely for all the videos of the world records, which you can find here:

Give it a look, there are a few others with some fantastic times and videos, definitely worth a watch.

Great times and videos man! You never know with Steam leaderboards since most of them are all hacked. I immediately thought of Lvl 19 which I tried tunneling a few times. Tougher than this one I thought.. Not on Steam, but saw yours on youtube too.

Thanks! Glad to see you so active in the community :D

Insane tunnel! I never thought anyone would tackle it so fast! :)
