You asked people to check the page, so that is what I did rather than a playtest — I sell asset packs on itch, so weigh that.
Your game’s name is cut off on every browse tile. itch serves browse and search covers at 315x250 cropped to fill, so a cover wider than 1.26:1 loses both ends. I downloaded the exact tile itch is serving (the 315x250#c variant off your own profile grid) and measured it: bright title pixels run into column 0 on the first line and into column 314 on the second. What a stranger actually reads is “e Adventure — The lost shards” and “(Dem”.
Pulling the title into the middle ~80% of the cover fixes it. Or drop the text entirely — itch already prints the title under the tile, so the cover only has to sell the look.
Second: the description opens with three all-caps announcements (Discord, DEMO 3, your personal page) before the sentence saying it is a 2D Kirby-like platformer. Put that sentence first; the announcements still work underneath it.
