For such a short game, it's still about twice as long as it should be. The gameplay is good and simple, but the levels don't have anywhere near enough variety to carry the full length of the game. Visually they all look the same and most of the main character's levels do a decent job introducing new ideas, other levels are a slog. Every map has a variation for all characters, and 2/3 variations tend to be repetitive and pointless, yet mandatory to a degree. If the side characters' missions were actually optional I'd like this a lot more.
