Very unexpected. That jet ski animation looks VE-E-ERY choppy. Are you planning to work on improving it? Gives me a headache just by looking at it.
Come to think of it the game seems to be limited to 60FPS, can the limit be removed? maybe that would help with choppiness a bit.
It's not the framerate, it's because they're 2D sprites rather than 3D. Characters are only rendered facing 8 different directions, so turning happens in choppy 45 degree increments. It's much more noticeable with large vehicles than humanoids or creatures. In this regard, small jetskis were a good choice. Larger vehicle sprites look even sillier when turning, think of Fallout Tactics for example.
Thanks for update, regarding my question about running, quote from dev blog below:
There is no running option - The main problem here I think is that backtracking through the areas you already explored, as well as moving through the non-hostile areas, such as the SGS, is too slow. I'm not quite sure yet how I'll address it. Just adding a running option is not that easy as there's a lot of stuff to be consider there and it would also need new animation on all those character models, etc. I'll have to think on how to address this one.
Now that's a really old quote. That was addressed years ago by increasing the walking speed (it used to be slower way back in early alpha) and movement speed increasing boots were added a bit later in alpha. Probably not the answer you hoped for, but there you have it.
