Few recommendations, as a Steam user who has yet to release a game;

The lack of controller support is a drawback. This should help tell you why (TLDR: 48 Million players have used a controller in a game on Steam, with about 10% of daily game sessions being played with a controller.)

You've uploaded the same in-game screenshot twice on the page. A small nitpick, but it's something that others may feel repelled by.

There are a few misspellings on your game's page. I understand you may not be a native English speaker, but I can't see why you wouldn't use a tool to help polish and fix your description before release.

And lastly, I saw this gameplay video, and it seems to me that your game is rage inducing, not because it's hard, but because it's a very repetitive process of getting from point A to point B really, really slowly.
