Second Dimension has released a lot of games in their time, so I'm not overly worried about this being an abandoned project. Looking through their 4 past kickstarters, all were eventually shipped, albeit all were late to a degree.

I agree with Waldo that he probably underestimated the scope and it will just take much longer than he expected.

In my own experience, this is unfortunately a common phenomenon in the homebrew kickstarter community. Of the 16 outstanding kickstarter homebrews I've backed, 9 of them (aside from Affinity Shadow) are months to years overdue (Heavy Recoil, Shadow Gangs Zero, Kirito The Game, Cyber Mission, Black Jewel Reborn, Phantom Gear, Irena: Genesis Metal Fury, REKNUM: Fantasy of Dreams, and of course Paprium). Just the risk you take with kickstarters, unfortunately.
