Well, this was a really nice game, I really enjoyed it (played v0.4.3). The hint system is very helpful and clear, you always know what to do or if you already reached the end of the content for the update. Art is gorgeous, characters are nice, story is interesting and lewdness is in the right pace, things escalating progressively, daring but with mutual consent. Thanks for that.
I came across the already mentioned bug of getting a black screen on the tree when she (cousin) wants to see more. I had to quit the game, load again from the latest save just before starting the quest, and the second time it worked fine, got the scene and the game progressed fine. But yes, there's something going on in that quest's code that makes the game freeze.
Looking forward to see more of this game
