So, let's see, how to start?
Well I liked the puns you made in some stages, like Opera and Safari.
The levels are pretty repetitive, but the bosses surely are not. Well, Chrome's pattern looked a bit similar to Opera, but it was OK.
And the art was made with Paint? That's something you don't see around too much today. It was fantastic, considering it was made in paint.
Music: A bit repetitive but good.
All-in-all, this is a very good game for the Ludum Dare 25. 4 Stars!
