block-chain was extremely glitchy. (sound was also very choppy during that stage, so it could have been running below its minimal functional frame-rate)

the physics on the blocks in general were an issue for me in development. i'm going to try to get a bug fix out there soon though! hopefully i can smooth over the audio there too. that one can be a little more difficult with browser-based stuff and Godot's current audio system, but they've been putting a lot of fixes in recently.
