Yes, slopes are not so important.

Use Entity, not GameObject. GameObject is completly abstract and can
represent anything, while Entity represents an object in the world.

Sector sounds good.

Quadtree sounds overkill to me, the tilemap already gives you direct
access to all tiles.

We want to avoid the discrete movement as much as we can.

Yes, player should automatically 'jump' (or be moved there by more
gentle means) into the right position if close enough.

PS: address@hidden should be the official list, the
nongnu one is however still mentioned in some webpages, need to fix
that.
