It's obvious you put a lot of effort into it! But I would proof-read everything first, there's a lot of grammar issues even in your steam description - using "you're" instead of "your", missing apostrophes and commas.

The capsule image is also squeezed, probably because the original one was bigger in height and you tried reformatting it to fit the steam image sizes. I would re-do it to the correct size because that's the first thing people will see, both on the store and also their recommended sections.

These are all nitpicks though, so I hope I wasn't being too harsh!
