Money isn't the issue here, it's the absence of the developer.
With money alone all we could do is create a new game, which isn't our goal.
Why absence? Maybe he's just taken playing a stall too seriously.
Seriously tho if he abandoned the game he could sell the copyright and let others develop Elements.
Otherwise again he could get funds to develop it himself. Plenty of options.
Plus Kickstarter isn't for creating Flash games, nor would too many people fund it like that.
The vast majority of KS games are flash games or similar stuff.
Many major Flash CCGs were Kickstarted, i.e. War of Omens was Kickstarted not too long ago and it's doing very well.
If anything it's a great time to kickstart stuff, these days you can get anything KS'd even video series about sexism in Super Mario.
It'd be a pity to see a game with a metric ton of potential abandoned.
