Decent little thing
While there is not much in terms of interaction, it is still good. There are a lot of areas where it could have been better, like just have a lot more pixels around. This even be thought of as a way for people to experiment with learning how to do Flash. I will probably never do any sprite work or any kind myself. The biggest suggestion is that you just have to put some music in. The audio portal aught to have plenty of things that might suit it. I still had to like it because of how many things you were allowed to do with it.
There could have been more pixels or at least more to make me proud of myself. I still recommend it because there are so many features! I can just spend all day looking for new things to do with my creations. It is a really good way to express your creativity, even if it isn't the most detailed game (?). I am sure some people were helped by this.
