This gives me the impression that it has been cobbled together from the assets of a MOBA wanna-be - especially that last fight with the three enemies in the tutorial stage. They look like they came from a DotA knock-off.
The other sign that gives me this impression is the user interface. Textureless gray boxes reek of default design options.

An ARPG and roguelike, interesting.
