Well, maybe not that much time; but, when making BlitzHolder, we've programmed everything with coordinates: thinking of a 1920x1080 screen (as for .exe and such). However, the web version is not taking very well such a size, and now we are trying to reduce everything. That will not be an easy task, once we need to convert every single script from a absolute position into a screen size relative. The good news is that once we do, we can basically change the screensize to any value within that ratio! (We will still keep doing minor fixing updates until that is done)
