Little bit of constructive criticism:
A) Begginning is spelled "beginning". (first impression of your game trailer is a misspelled word, not the best)
B) Try getting me interesting in the plot of the game.
C) "and stuff very fun" just makes you sound desperate and like you ran out of material to describe. Try; "A game I made with Unity in X number of days to learn a skill." Tell a story of the development or at least a paragraph or so of real discription.
