There is a tutorial in the game - go and play that for instructions. All levels in the game are possible, but the last level on each section is very hard. If you find any glitches please post them in the comments for me to look at. In the next update (1.2), there will be: Songs and other sounds, maybe A new ship (HMS Illustrious) + 2 new plane types + new levels (This will take a while)
