I’m putting some serious consideration into a next incarnation of this game, despite the other ideas floating about in my head. At its heart, the game will be the same — but there will be more challenges, more variety, more abilities, and more things to learn.
It’ll very likely be done in Flash.
But as of currently my plan is to keep it similar enough that being good at Probability 0 will result in being at least decent at this game from the start.
Altogether: It will be familiar, take a lot from the original, but different and fresh enough to stand out.
