Reminds me a lot of Dumb Ways to Die but with sciency scales instead of more general minigames! I think it's fun, but it gets boring after a while, probably because it's the same few minigames with very little content variation? I could see this being a fun alternative to Dumb Ways to Die given that the ruler segment almost always gave me a "deer staring at headlights" moment when my brain momentarily forgets how to read a ruler without all the numbers :p
