Just an advice. If you wanna be noticed your first demo needs to be atleast playable. However this is an absolute mess. It will be much harder to work from there.

2 things
1. i didint see any mention of this game being a prototype on this page it really seems like a full release/beta
2.id also like to mention that black on grey on grey is a horrible choice for a page design as their all colors that slowly merge together id maybe suggest on changing text color or even background color to make things easier to see
