I've never played this series before, but took a punt and I absolutely love them - just a fantastic package. Well balanced and with a difficulty pitched about right for the casual player as well as the more hardcore. Graphically it's full of lovely details, reminding me a lot of the Bitmap Brothers work in particular. Good pumping soundtracks too. A little work needs doing on the UI outside of the games themselves - particularly making them more gamepad accessible and making restarts easier. Hopefully in a future update. Don't miss this one.
