It is dependent on your graphics driver and your graphics card. The browser has a feature called WebGL that allows the game to use the graphics card to render images. This plugin NEEDS WebGL support. But for some drivers the browser inside the game engine decides that the GPU should not be used...
In case someone else got the "Cannot read property 'blendModes' of undefined" error, that's probably because your browser does not support WebGL. For me it worked in chrome, but not during playtest.
For a solution, checkout this thread - the part where you insert "--ignore-gpu-blacklist".
I prefer single roommates. After a hard day, all you want is sleep. I went to bed at 12. I was awakened at 2 because of my roommate laughing and whispering and stuff with her boyfriend on the phone. I didn't want to yell at her so I had to bear that cringy lovey dovey convo for half an hour, before I got so bored that I fell asleep again.
