I was enjoying this game, I felt that the short but challenging nature of the stages was fun. But then the stage design started getting a bit sketchy around World 6.

I was not prepared for World 7.

Every level was a slog, each one threw so much stuff at me that there wasn't any chance for me to stop and process what is going on. It got to the point that I was dredding staring another level, not helped by getting a Game Over every other stage. It may not effect progress but it sure was demoralising.

If this game had ended at World 6 I probably would have marked it down as good but not my favourite.
