For a long while I didn't know how to use nodes. Maybe the game could have explained that after you become able to craft them. Also, I prefer manually advancing text (like in the games that say "press enter to continue") rather than have it on a timer, unless there's voice acting, and even then I'd like the option to skip it ("I've played this game several times, let me get past this cutscene quickly") or pause it ("something just happened outside the game, let me look at that and return to the game after that, don't force me to watch the cutscene to the end first") and I guess being able to force it to auto-pause after each sentence might be useful for slow readers ("I'm not a native speaker of English, let me look that word up in a dictionary before you show the next sentence").
I could have got further through the game, but having had to restart it just to see the controls, I'll just assume there's stuff I haven't seen and it fits the theme. I think it's fun in Chrome, and unplayably buggy in Firefox. But at least you warn that the audio is missing there, so I tried it in Chrome.
The art looks nice, especially the cutscene art. And the music sounds interesting while fit for an action game. I can sit and listen to it without playing the game, and it doesn't get me bored, at least not for the short while it's taking me to type this. And the main menu animation moving to the beat is a nice touch.
