Hi Moosefoo! This is possible to a limited extent currently. If your tiles are 16x16, you could create a character that is larger in scale, up to 32x32.
In the example below, the tiles are 6x6 and the large character is 16x16. The character will still only take up the space of one tile though, so there could be the issue of its model clipping into objects or other characters in adjacent tiles.
I do have plans to eventually allow characters to take up multiple tiles which should help with that issue.
