marketing failures?
how would you differentiate them with marketing? "yet another color bubble popper!" "yet another side-scrolling shooter where you kill the undead!" "yet another match three with fruit!"
i'm not sure i agree with your assessment as to marketing failures. if you said me-too-market-fit, however, i'd say you were on to something.
their level of polish is pretty nice, so they should step out of the lottery and make a non-me-too quality game. i bet they would be pretty successful with it. in fact, if they keep with it, i'd put money on it they'll eventually be very successful.
