Use the arrow keys to move. Try to make it through 100 extremely, extremely hard levels. No,seriously, some of these levels are MIND-BOGGLINGLY hard. The final boss took me 2 HOURS to playtest to make sure it was possible. PS: Nobody I know has made it past Level 9. With that being said, try to enjoy.. If you can. Yes, ALL LEVELS are possible. ...I know so because I had to go through the misery of play testing all 100 levels. You're welcome.
