Kivi's Underworld has another very positive review over on Jayisgames/CasualGameplay.  A quote:

As it stands though, Kivi's Underworld is an awesome addition to the Depths of Peril series and will no doubt be well-received by fans of the genre. You can have the same amount of fun in a 20-minute session that you can in two hours, an attribute that's pretty rare even in action-RPGs.
