Version 1.0.1

• fixed a crash in stage 1-3 when the big enemy causes the players to spin around
  
• fixed some enemies in stage 5-1 going out of screen and preventing the player from advancing
  
• fixed gamepad-cursor in stage-selection menu skipping over an area if all stages of that area are not yet unlocked
  

I'm still investigating a crash on startup and a crash when entering stage 6-1, and will try to fix them as soon as possible.
