Love the 9 screens featuring the classes.
Although the background music is good, the video should follow the flow of the music (change screens every rhythmic bar)
I would replace 0:06 - 0:13 because the video isn't full width. Also I would change the background of the text rather than have a text outline.
Something like this:
When I originally created the video, I incorporated "play against thousands of users", "comprehensive anti-cheat system", etc. - I used those phrases because they were used as the game description. Those phrases were literally as the game was described, and I do believe the game had a player base of at least one thousand independent users.
However, after 3 months pawngame has less then 500 users. I think it would be false advertising to use that video in practical advertising. Wouldn't it be unethical to falsely promote this game?
