If you want to catch viewer attention then you have to gain his interest somehow.
Picture(static or animated) is the most simple and straightforward way to get attention and it does not require any work from viewer, video - harder to process and I’m not sure it’s going to work if viewer is not interested enough(but if he is - it is a great way to give more serious information), text works good ONLY(IMHO) if viewer already interested and willing to know more about your project.
In the beginning the most important things(imho) are: WHAT you want to show to user and WHY user should even bother. Start with juicy cool pictures and very short texts(Single line phrases) that defines what exactly are you showing and why it could be fun for user, then use smooth transition with short video(for example) that reveal a little more basic information about your game. If viewer is hooked - he will proceed to the full text, because he is interested and want to know what all the fuss was about. And if not - let him leave without overloading with useless information.

Intro: Nice logo, no additional info. At this point I don’t know anything about your game. The only association - bomberman.
Body: Wall of text, no graphics. No mention of ~genre, visual details(first person, third person, isometric, 3d, 2d etc) and fun elements. Your second line is basically a linear list of accessible actions to player. It’s like “Use pistol to kill enemies at close range. Use rifle to kill enemies at long range when they run into your bullets. For final showdown, pick up the shotgun and kill enemy!” I think you got the idea.
You should encourage viewers to explore your game with stuff that already in game and simple enumeration won’t do this job(imho)
Video: Cropped gray toned video with 2 dudes repeating same actions over 4 minutes ;_;
Sorry if I’m being too harsh, I just want to highlight stuff I think not good as it could be.
Also, I tried to play alpha version, but I had infinite background picture after I pressed “Join” so I had to Alt+f4 >_>
