The graphics are well-suited for the early days of the comic while still giving that retraux game feel.
The controls and the level design doesn't always synergize very well. Annie drops like a brick one she hits the peak of her jump arc. This makes it difficult to navigate through the air for the jumps that are over wider gaps or are landing on narrow platforms. The ladders also feel a bit off, since you have to hold up to stay on the ladder, so you're always going up the ladder, making it more difficult to do timed-jumps from the ladder.
