This week I ran into the same introspective question that I hit multiple times with Robo-Ninja: Is this game going to be any fun?
It's just really hard to tell, as the developer. I'm way too closely attached to every minute detail to have any idea if this game is remotely fun to play. I'm pretty sure that's what happened with Deadly Towers. The only explanation I can come up with is that they didn't get outside input to tell them how bad their game was, and they were too close to see it. I really don't want to make the next Deadly Towers.
