Many thanks for taking the time to offer feedback. I will try to address all your points in order.
+ I personally think it helps to see the cost in dollars on the tier. I know it has helped me in the past. I know I am familiar with sterling but I understand that many people might not be, and I'd rather avoid the disappointment of people deciding on a tier only to click and then realise it is more expensive than they realised. So I thought including US dollars (a popular currency on the internet) would help at least some people avoid that.
+Unfortunately, I cannot afford a trailer, so this is not something I can do.
+Backer-only updates are now available for everyone
+I'll reply to your TROS suggestion in your other post
+There is now a discounted early-bird tier
Thanks again for your feedback. Please feel free to look over the updated KS once it is completed and let me know what you think.
