Just dropping my 5-star rating because the game deserves every support it can get. More devs should take notice on what makes this genre good, and Summer Heat is one of the best examples.
About the GRAPHICS and renders, including posing and quality, simply put, they are top-notch, and once you're looking at them you'll realise what I mean. The STORY is a bit on a prologue sequence but the characters feel like they have their own personality and ambitions, all in just four somewhat short updates, which says a lot. I want more and understand where the plotline will go wrong (the horror tag is intriguing). The phone application needs some improvements but for not it doesn't really matter all that much.
The only negative part that makes admit it might not be a true 5-star rating right now, is how quick and short the updates feel. But that's also because the game is so well made that you constantly want more of it. But considering the amount of content and the quality it provides, it weights around that rating, and with more updates it will be easily considered as one of the best produced AVNs around.
All and all, support it and make it bigger. It won't disappoint in the long -run, I am sure. It is a bit short right now, but very worth your time... not many games can say that.
