Some assets are from Unity's isometric demo project, which you can learn more about here. These include:

• Tiles (palettes, sprites, colliders, ...)
• Characters (sprites, animations, movement scripts)
• Basic setup for isometric (scene, camera)

• Can generate random square maps of variously shaped rectangular rooms (hallways, single block rooms, big chambers) connected by bridges
• This also sets up colliders so you can't walk out of the map
• Pathfinding methods to get AI characters around the map
• Some basic content for rooms (like pillars in hallways, shown below)
• Methods for creating elevated platforms and stairs, complete with colliders

1. The stair colliders aren't set up 100% perfectly, so part of the stairs is blocked

2. When not placed at the edge of an elevated platform, the stairs remove one top edge collider next to them
