The product link that you used does not lead to a specific game, but to a series of games, thus the hunt has been delisted.
PG # 3 - Product Link
SteemHunt "accepts only the following 4 types of product links:
- Official product website (Should be the product's website, not the general page)
- Major app store link (AppStore, PlayStore, etc)
- Crowdfunding sites (Kickstarter, Indiegogo, etc) - The funding should be active status or fully pledged. The project that has failed to be pledged won't be accepted.
- Github, Bitbucket repositories for open source projects.
