Hello Rajmahal,
On the site https://www.assetstore.unity3d.com/en/#!/content/96784 , below sections Pack Description and Asset content is “User Reviews” section . In it you should have “Write a review” in right top corner of this section.
I think I had this happen with another asset. For some reason the button doesn’t show up but then it appeared later. Might have something to do with the fact that I redeemed a code.
I really liked this asset, there is some points i can give, it seen that all the background are the same, so you don’t need to have a PNG for a transparent shield and one with the purple background, just make a single PNG for the background and put on top of each item, you could also use a shader to color each background, but only if really wanted to. That being said is a pretty good asset and some nice drawings you got there.
Yep, i just got some time to try the asset and wrote one. I think you need to download the asset first before you can write an review.
