DS best-seller in the making?
Seriously, this could be the DS's answer to Alien Hominid. All one would need is a good effort at marketing the game to a developer (Behemoth, perhaps?), and some fleshing out of the current game. I'd recommend a minimum of 11 more levels, with a little bit more (and better punctuated) dialogue, maybe some voice acting. And some minor cutscenes, like in the beginning of the current game. Otherwise, you're set: obvious stylus functionality, certainly capable enough of utilizing both screens, and...well, that's it really.
I look forward to future levels...if not on my DS, then at least on Newgrounds. Thanks for a cool experience!
