OK, so there seems to be a lot of issues with the text. I've actually seen it once and it was fine after a reload. So I do think it's just trying to do something with text before it's actually loaded. Because it's just CanvasAPI and I have to recolor it per pixel on another canvas, it wouldn't know there's no image yet and my code probably just assumes it's loaded. It may even be the same issue as CrankyCranton, just his canvases start with random data... I'll maybe upload another fix on Friday.
Anyway, I uploaded a new version which allows you to have cookies off. It just won't save your progress between page reloads.
I'm glad you could play it finally, haha! Thank you. :)
No text =/ And there were no any errors in the console other than returning existing sound you mentioned.
