I gotta hand it to Pixelbite, they did a really good job with Space Marshals. I just played through the third chapter and it has been a good mix between challenge and fun.
What I like about the game are things like the clues you have to look for in most missions because they make you pay more attention to the level design and therefore youll enjoy it more. It certainly deserves it!
Also, there is potential for replayability because each mission rewards you with a number of goodies you can choose from. If you did well and reached perfect score youll get to choose from more rewards.
And those rewards can create new styles to play or just allow you to mess around a little.
In conclusion, Im pretty happy Space Marshals was offered as App of the week because I got to enjoy what adventure of a game Pixelbite has created.
If you are looking for something to keep you busy then this is your opportunity.
PS: I hope therell be a new storyline soon!
