A little over 9 hours to beat but I had 2 game crashes on the final stage. It would have otherwise taken maybe 5-7 hours to beat. At around 7 hours in the data menu time is when FreePlay seems to unlock (Unlimited continues). For this run I had 99 continues and 76 remaining when I beat it (Used 24). This attempt took around 1 hour 40 minutes but is edited down. Check the unedted version here:
Deaths edited out. I edited straight to the checkpoint restarts if I died on a checkpoint. Also showing most of the ship choices and restarting checkpoints fresh with no starting power ups. I may make a tutorial for this or the hardest mode. Will see if the game crashes again on the hardest mode. If so I may not waste my time working on it until after some patches.
