I am SO glad that they decided against using that artistic style for the final game. I especially wouldn't be able to stand Samus's bug-eyed visor that she has going there for very long.
Huh. Wonder why they decided not to include the power grip ability from the beginning, as that video clearly shows it being there.
they decided that 20 power bombs would be a too nice number and killed one to add an additional percent (an unskippable one at that, making the idea of 8% impossible)
