Game probably wouldve taken 5-7 hours to beat but it took a little over 9 hours due to two game crashes on the final stage. This is the main reason Im hesitant to work on the hardest mode and am likely done with the game now. In this tutorial I break down all my strategies, ships used to beat normal. Many exploits as well, including how I kill the final boss in 12 seconds and how to unlock Freeplay (unlimited continues). My review is coming soon. In that video I will address all my issues with the game and break down the core gameplay. Here are the passwords for the two ships I unlocked,from GameFaqs under the Switch version:
