It's a good game, if you like muscular gym girls, it's definitely your game...
Pros:
It teaches a bit about real life exercises...
Audience music is okay...
Diverse heroines with a fun personality...
Diverse poses (each time you increase level you get a new action)...
It's got Voice Acting, I personally liked it...
Cons:
Music can get repetitive...
Dialogs repeat over and over...
Personal review:
I like that it mixes rogue-lite elements (yoga and massage upgrades), gym, sex/porn and common fantasy monster characters that basically everyone has seen at least once, and it's put up in a vanilla heartwarming way...
Another thing I really enjoyed is that, it's a game with Male on Futa elements, something that is incredibly rare on any other game, but I understand if it's not everyone's cup of tea (especially since a lot of people who consume futa content prefer to see "big futa dommy mommy fucks guy into submission")...
