The World's Hardest Game 4, True 100% Run (All Paints, All Keys) 

In this video I play The World's Hardest Game 4, not only getting all the paints, but also collecting every last key. With the exception of Level 5, getting every last key did not make the game much harder. This was the first time where I beat the first four levels in under 100 deaths and the first time where I beat the whole game in under 200 deaths. I was hoping that I'd beat the game without the square complaining that I've been in a level for a whole level, but the last five areas ruined that for me.
Progression of the Death Count:
Level 1 Complete: 8 deaths
Level 2 Complete: 15 deaths (+7)
Level 3 Complete: 26 deaths (+11)
Level 4 Complete: 98 deaths (+72)
Level 5 up to C2: 150 deaths (+52)
Final Result: 166 deaths (+16)
