Spin Tiles 2020-08-11

Thanks to thepsynergist and Barrel's O'Fun, a number of bugs were quashed in this update!
For starters, when spinning, one frame stays on longer than the rest (I think? I personally can't tell but that's fixed now)

Also you can't start running in the middle of a spin tile, causing shenanigans with the displayed sprite.

Finally, you can no longer sprint head long into a spin tile and carry that speed through.

This update adds in Stop tiles, which is a thing, apparently? Never really played much of RBY, FRLG, or HGSS, so I never saw them.

Stop tiles do exactly what you think they do, stop the player dead in their tracks if they're spinning.

If you don't plan on using them, just set the terrain tag to -1!
