The sixteenth build, made in Scratch 1.4.0.7 (I do not have a linux terminal available for 1.4.0.2 through 1.4.0.6.) Added mobile support, in the form of mobile mode, with the WASD/Arrow Key Indicator being repurposed as a d-pad. The secret costumes are accessible through slider variables. That's all for Scratch 1.x, on to Scratch 2.x!
Credit where it is due.
