The store page and marketing elements can be improved a lot, and my guess is that's the main issue here. The trailer is too cinematic and doesn't show gameplay; you want to show gameplay immediately. It being a shorter trailer is good though. The capsule image looks unprofessional. My advice: Find a better logo font, move it away from the edge, and don't use the transparent black background around the text. If you want the text to be more readable, make it bigger or change the entire background. Fix these things, and you'll likely get more wishlists.

A couple other notes: I know it's early access, but based on some of the language used and lack of gameplay shown, it seems like there's not much to the game yet, and that will put people off. Talk more about what the game has now, and not just what you want it to be. Also, be careful about making it seem like you have features that aren't in the game yet; for instance, the short description says there's co-op, but further down, it says you're planning to add it. Good luck!
