I have to give you points for inventiveness. What I didn't like about this was how difficult it managed to be in such a short time! I had no idea where I was even going with this! At first, I thought I could maybe take my time, but it quickly goes to the next part, or whatever it's called. It's hard to suggest changes, because it's pretty much fine the way it is. It's just very difficult.
It can sure be a pain when you can only last four seconds. You'd think a game lasting only a minute wouldn't be that difficult. You are definitley trying to make us work hard. It's unbelievable how it's done with so few graphics! It seems like you wanted to make something innovative.
