Thanks for playing! I'm glad you're enjoying the writing - I had a lot of fun with it.
That's an interesting suggestion regarding Brain. You know, for the longest time I didn't quite register that the portrait didn't actually go with the sprite. But yeah, the fur collar kinda implies that there's more to the guy than just a head :)
There ARE other humanoid creatures on this planet, so it wouldn't be too crazy for him to be one. Maybe I'll do that with the next update. He wouldn't be a *human*, though. There ARE actual humans in this world...or rather, there *were*. You'll find out if you keep playing!
Oh, and I just released an update that rebalances some of the later bosses. If you download it, you can transfer your save data to the new version by opening the 'www' folder, then copying the 'save' folder inside that folder into the 'www' folder of the new version.
