Very nice, like it a lot, understanding how vision worked took a bit but it was neat once I understood it.
Thinking about and discovering use cases for splitting was interesting.
Atk speed stat is slightly hard to understand as is how armor works(it seems to not be a flat damage reduction).
A more obvious and clear hp displays could have been nice, or you could have just hidden it entirely and made vision the only info you get, it being there but needing to "work" to get the exact number is somewhat annoying.
