Great game. I spent an entire waking day playing, went to sleep just after unlocking a portal, and now am awake and an hour later have H, K, I, and H's friend maxed.
I was hoping for a new event for K, and more progress for I, but it's looking like all one can do is day in and out make money.
For This style of game, it is much more rich and longer lasting than most. The art is great. The attention to different kinks is outstanding. I particularly hope for more lesbian, threesome, and maybe some pregnancy in the future, and especially a lot more feet stuff.
I'm very anxious and excited for the next update.
I can only suggest the obvious (more story for everyone, and more portals to open, and maybe have portal friends stay unless more original portals will come)
