I replayed this a couple of times and In the creators next game some improvements I could suggest for them is the following feedback to make the next game more enjoyable / popular all around:
1) Don't make it so it needs an external walkthrough. Games that require a walkthrough are less popular. I'm not saying it should not have complexity or branches. It can be made complex and also not need a walkthrough. This can be done easily by having many choices not meaningful and anchoring which path it is on to a very small number of obvious choices.
2) Jumping from location to location too much: If you jump around a lot from place to place to place without good segways, or much time at each location, or showing much of transport from place to place it can confuse players. Spend a little more time showing the buildup. For instance you shouldn't jump from work to the beach in an instant.
3) Random time jumps... "The following monday..." "One week later"... It's okay to do such things every so often, but overusing it can be bad and should be avoided as much as possible. I mean even once it's like "4 years later" like wtf?
4) # of branches should = # of endings no more, no less.
5) Adding many more girls than those who you get to fuck is not good. So, if there are like 10 girls in the game and only 2 are fuckable wtf guy? If you can't dick a girl don't make the player waste time on her. Because people pretty much don't care. Few things piss a player off more than a girl in a game they like and then having them not being able to get that booty on any routes at all no matter the circumstances. Especially if it's a girl you have extended interactions with. I'm not saying you should be able to magically fuck the waitress at the diner from day 2 that you met once that was kinda cute in every single game. Inevitably there will be some booty you can't score... However, if you meet a girl more than twice she gotta be fuckable somehow. Definitely avoid having a girl in the cover image who you can not fuck.
