4 Years of Service
Just a comment on the driving part. While talking in the trailer BEFORE setting off the MC says he found a place they can part (typo in game should be park) overnight that isn't far away. Also, they leave at (or shortly after) noon and arrive with enough time to set things up before dinner. This leads me to believe that they only drive for 1-2 hours so while the lap sitting might get uncomfortable, it wouldn't be excessive. Making MULTIPLE stops to change drivers would NOT make much sense in that short a time (April only has THREE orgasms as they drive). I WOULD like to see a Mod or bonus option that allows us to watch all the scenes, but that would be an extra NOT needed as part of the story.Indeed very nice so far! The character design of the sister and the mother are really beautiful. And the renders per se are also very good.
I cannot judge the story so far, especially since nothing about the "apocalypse" is mentioned so far. But it could become interesting.
This game promises to possibly become a diamond.
But I think there are also some things that could be improved:
The MC as a boy looks like a boy with an adult head. That looks weird.
The choices and its result could be more plausible. Obviously having sex with the little sister or not decides about the options who sits on which one's lap during the ride and who drives. That really makes no sense to me. If you did something wrong right before the ride, for example if you treated the mom badly so that she does not want you to drive or something similar, that might work. But this way it is just like guessing and trying all combinations. And that can be frustrating. And plausible results of the own actions are very important for a game, I think. That they are plausible for the developer in his or her head does not mean they appear plausible for the one who plays.
Besides, if there is no reason for someone not driving, it would be nice to have them all drive some part of the ride. During the first part the MC could drive and the sister sits on her mother's lap. During the second part, the MC could drive and the sister sits on her brother's lap. And during the final part the sister could drive and the mom sits on the MC's lap. They would only drive on empty dirt tracks and only the MC would exactly know the way then. So he would have to sit in the front, but that would be no problem, because on this last part of the ride they would not meet anybody. And this way all three scenes could be shown...
When they arrive at their destination and are all standing next to each other at the lake, the MC looks too old. He looks like the mom's older husband and that simply does not work. Plausiblity again.
During the ride, even if you have enough points for the option to do something with the mom, in the other option (that one to not do anything) there is still to see, that you have not enough points. That makes no sense. You might want to correct that.
Finally, knowing the total sum of points of the mom is nice, but knowing those of the sister would also be nice, if there are points for her. And knowing, when a decision has given you a point, would also be nice.
Aside from the game, I think it is very important for a developer here to stay in contact with the fan base and the potential supporters in order to gain trust and then support. But that's just a friendly advice for the future.
I wish you the very best for the development of this game!
Now a couple typos:
1) When talking in the trailer before leaving the MC says that he found a place they can PART overnight. It should be PARK.
2) When looking for the ladies before leaving and choosing Emily we have the option to 'Check OUT her out'. This should be 'Check her out'. The extra out shouldn't be there.
3) After #2 Emily asks, 'So what do I owe the pleasure'. This should be 'So, TO what do I owe the pleasure'.
Just some thoughts.
Hopefully "Apocalypse" will become just as good!
