At the earlier levels it seemed to work, but later on in the game it becomes unplayable because of broken textures. At first it helped just zooming in, but this is no longer the case. Using Windows 7 an newest version of Chrome. Seems to work in IE and FF, but as all of my progress is locked to my G+ account, i would really like you to take a look at this.
Do you think it’s the same bug as this thread? https://github.com/codecombat/codecombat/issues/1933
I wonder how much RAM and graphics memory your computer has? Trying to narrow this one down.
We currently don’t have a good fix or way to debug it, so it might be worth logging into your G+ on Firefox for now as a workaround.
