The danger of a "new style" is that we will have to re-do everything to fit with the new style. For now we should focus on developing the main peices of the game that we need and haven't done yet.
(I do like the new style, but we should wait a bit before switching)
Well let's say the change to the new style will be pretty easy and most of the people won't be aware of it since we will be using the same graphic, simple rescaled. With the time we will gradually replace everything with the new style. (If it's worth it)
