Hello, Im new to speedrunning and want to try speedrun this, However I am on chromebook and as I press tab to try select, Nothing happens. Is there a way to do it on chromebook or is it a lost cause?

Look up if you can install the adobe flash standalone player, then download the .swf file from here. I started speedrunning this game on linux with no issues performing the bug, should be the same I think. Also chromebooks absolutely suck as a product but that's besides the point.

Alternatively, play the glitchless category, I think it's more challenging and less stupid

install the Ninja Kiwi Archive from steam. it still works on the Archive's version of BTD2.
