Definitely an interesting and slightly challenging game to get all the way through but I really enjoyed it. There was a lot of good humor and pop culture references that add to the value of the game where other games are just trying to get the English right. The CGs and animations are nice quality.
All that said, there definitely were some lacking aspects. Given the amount of time I had to invest in completing the game, I was pretty disappointed that neither Katara or the other MC in the firebender area had a true "public humiliation" sex scene, as the game strongly hinted at those as a possibility the whole time. The window ending was nice, but Katara's ending was fairly mediocre.
Obviously this could still be in the works and be improved upon in future versions. As it stands I'd say 4/5. Worth taking a look at if you have the time to kill, but slightly grindy (unless you use cheats)
