Ok here's my comment as a player, not as a game dev . I'll be as honest as possible and try to avoid any conflict of interest.

I've played it regularly before it went on Nutaku.
I like the general humor... the dating system is quite fun with some girls having a nice persona, I quite like that .
About the fact that it's a Hunipop clone, it's partially true since HuniePop is not a F2P but well "some parts" are an obvious "tribute".
About paywalls, and the game becoming too hard too soon.. can't agree more. I've spent over $50 on their .com and it was not enough to have a smooth experience.
In general, the Match3 experience is kind of fun but some puzzles are just impossible and that's frustrating... I've played extensively Candy Crush and I admire their algorithm... on PS there's way for improvement.

As a general touch I like the art, do not like the focus on crude language (one girl could be crude, but they're all hardcore...).
But I've seen their game improve a lot these past months (several interfaces being totally revamped) so I believe there's hope and I wish them success .
