I just backed you guys 20 pounds but some honest feedback is have you guys read the rewards? THey are pretty bad and a lot of them don't interest me at all.
I'd recommend comparing to other games like planetary annihilation, star citizen that did really well.
People want exclusive stuff even if it doesn't do anything special (ie: still balanced). but maybe some glowing armor or a fancy in game badge or better starting equipment.
Anything really, doesnt need to be over powered or could be purely cosmetic but not 1 of the rewards offer any in game recognition of reward. I know there is one tier that lets you recommend a weapon be made but this sounds more like work to me so again, same with design terrain etc. Obviously might appeal to others but just wanted to share my thoughts.
Other games might give me a ship, a different colour hero or armor, and a founder badge in the forum and maybe in game. Still 20 hours left, I'd recommend adding something like this if you want to make and exceed the goal!
Go for it
