I don't blame you for thinking that you're thinking, but if they do that, they might not even make enough dough to pay salaries and they will close shop and oops, no toy bot 3. I guess we just have to accept that other ppl need to pay their rent too...
As a fellow developer, i know how much effort and manpower it takes to develop a polished platformer like toy bot. Trust me, if this game is on the DS, it wouldn't be $4. They mentioned that there will be 3 episodes so the game in total is $12. On the DS, it will be a $30+ affair.
I heard this 2nd episode is much longer too, i'll give it a try tonight.
