Seems like 1.4 download works a little (lot) slower than 1.3? If I had to guess this may be because of Web or something, but Forest Moon is much laggier than it used to, aswell as all the weapons (including punch) freezing a little the first time they're fired.
There seems to be a major shader compilation slowdown in web builds, a quirk of how the engine game renders the game in the browser. I've looked into workarounds, such as pre-instancing every object before the title screen, in order to compile the shaders before gameplay. I should be able to add that later down the line.
