the design is very good and the website is beautiful but the time speed of website is booring try to compres the image files not much than 300 bytes or less, and seo the website , write somthing for the description of your games.
It looks good, it remains me to Friv, I think if you manage to build up a good starting traffic you could do very well with it.
Your arcade website is pretty nice, but I recommend getting a better design. Having all the arcade games as little icons spread out all over the page doesn't drag me in. It annoys me that I have to click on a game to find out what it is. Some of my suggestions are adding the games into separate categories so people may play them. Get a new logo that will attract people and make your arcade look professional. Overall you have a great variety of arcade games to play, but without categories it's bothersome. I rate this arcade a 7/10.
I think both sites look good, but could be a little more unique between each one. Took a minute for me to load both sites, but could be my lower DSL connection. Besides that I like both of them still and will be book-marking the physics one since I love those types of games.
