When I wrote my original version of Color Collapse last millenium, it was in C++ for Windows 95. At that time the shareware scene was still strong and I had noticed that there were a lot of Tetris and Columns clones appearing. My personal design philosophy is that if you are going to "pay hommage" to a game, you should always have something original or new to add to the game. Obviously, there are exceptions to this rule (such as for existing card and board games) but I've always tried to put my own twist on any game that I am developing. With Color Collapse, that twist was to have the game board filled in at the start and the goal of the game was to clear the board. I don't know if I was the first person to come up with this idea, probably not, but I was not aware of any other game that did this when I originally created the game.
When I finally decided to play around with web development a few years later, I ended up having to port the game from C++ to the then relatively new Java platform. Last year I was going through the games I have created for the BlazingGames site with the goal of seeing what games could have enhanced versions created for it and came up with a lot of new play modes and special tiles that could be added to Color Collapse so decided it would be a good upgrade candidate. Unfortunately, before I got that project started properly, my mother was hospitalized and later died of cancer. The fact that my mother really enjoyed this game both has me wanting to finish this enhanced version while making working on it emotionally hard. The fact that the 2012 meme can only be exploited once dictated my plans for 2012 so this years releases are pretty tied up.
This is one case where having too many options is just as bad as not having enough. About all I can say at this point in time is that the Color Collapse Plus project will be the site focus of 2013 (subject to change due to unforeseen factors or the incredibly unlikely event that the world really does end) and will be in HTML 5. The how is the tough question.
