game already looks really nice so far, I like the simplistic look of the maps, reminds me of Portal. This could allow you to focus more on mechanics and such for now.
you should get it out and see if we could get some sort of release on steam to fund further development.
I'm not sure if kickstarter is a good choice, i remember some game publishers do not like to use kickstarter, but i forget why
there is a kickstarter type site that is altcoin related. something called StartJoin. I will have do more research on it.
