Creating more spawn points

Besides random spawning monsters that I have created, I try to create more spawn points type which are:

- Player
- Environment
- ?
- Treasure
- Item

At the first time, I confused about where to place the spawn points, but after that I think if I just keep thinking only I would not solve it easily, so I decided to do it roughly first while generating some more ideas.

Currently I found it complicated because there are so many spawn points and other objects.
