I found 38 Wizmagonster. Are they all of them in the Demo?
I also found these bugs.
I also found bugs with the well:
Apparently you can change you team and the sprites of the "followers" won't change until a next screen change.
Also, there is a weird bug with changing teams where your team disapears all together in the well menu, but reapears later. However I could not replicate it.
