Hmm, that may be true in some aspects but it's not how I work. I like to get things as feature complete as I can do so and then get to squashing those bugs. Especially when I know fixing those bugs aren't going to be a big issue. So I can focus on adding in the features that I know need to or should be in the game, in my opinion.
I mean don't get me wrong you are correct. The things that i listed that I want to add may or may not get added in the next few days. It's all about priorities. Such as sound and the line meter. I can see myself not having the time to finish this since this project is due on Tues. Power-Ups may be something else that I won't get to so most likely from this point on I will be bug squashing, but it never hurts to have a list of what you want to get in if you have the time later on.
