was I really just a shark eating my fellow humans?
SURE WAS
Looks great.
about speed "As the link is an older version of the game, there is small bug with speed for shark." - if up arrow was to make faster then it didn't work at all - but this you said is older so probably fixed.
I'm currently at work where it is running XP and stock graphics with 2 yr old drivers (work pc so can't update)
that being said game was consistent speed throughout and the humans falling moved steadily and much quicker than shark. The mine also was quick and didn't look like had framedrop.
can you say where frame drop happens? Like have you moved far on layout? Many humans?
Do you have webGL enabled in settings?
perhaps a screenshot of properties?
**EDIT**
I see you are looking for Android export. how?
