Thanks - and I've just checked out your game too! Great stuff
The trick for massive scores in Get Knotted is combos .. eg, a streak of 3 (closing 3 loops in a row) gives a x10x10x10 = x1000 multiplier. So you can get 2m+ from the last loop in the streak if you time it well. That allows you to clear any level :)
By the way, if you you like drum based games, I did this a few years ago that you might like to check out: Drum Cloud by tgd20 (once you've rated all seventeen billion GMTK entries ofc! :) )
