The game can be easily beaten by grinding on 8-Bit World part 1. The blocks along with the mushrooms, bombermen, and goombas gives plenty amount of coins for you to collect. I get around 1.5-2.5k coins per run. Use the second ship (Octopus) and it's power will drive you through the map easily. Invest in coin magnet early for easier collection. Then grind to your heart's content. After all that the rest of the game is a walk through the park. Thumbs up so that people who are having a little trouble (though I don't really see how) can see and beat the game.
this is sum dumb crap when you reload the button sumhow sticks and whenever you shoot it reloads again wth it doesnt stop reloading every first shot now
