This game was fun for the first few levels, but quickly turned into tedium and frustration. The controls are badly placed in awkward positions on the keyboard, and things like walljump only seem to work half the time. If this game were only the first few levels, it would have gotten a 5. I'm wholly convinced that anyone that plays this game all the way through only does so for the achievement to satisfy their OCD
Good concept, but takes too long to make money. The difficulty difference between levels is too great to allow a quick play-through without cash farming.
