Maybe I wasn't specific enoguh. By stretch goals I mean smth like this.
If We hit 10k $ and if you have Option, lets say D, you will receive extra 'item'
If We hit 15k $ and if you have Option, lets say D, you will receive extra 'item' + plus smth else.
On the other hand I see that all options are real good value for money! But it may be not so obvious to all backers.
And yes, the lack of time time limit is also strange thing. I think that backers are more eager to support campaings with time limits, because they know exactly when they receive their items. Moreover, lets say I am backer with 200$ per month to spend on such goodies, and I see two interesting campaings, that one ends in next 20 days and the other has no time limit. How do you think, which one do I choose?
Thats just my personal consideration, I am not an expert, so dont take it too serious. I am keeping my fingers crossed that you will reach 8k. I guess it will get better when you hit Beasts of War
