Hello everyone,
I know the engine shift has caused inconveniences to many but trust me that this change was necessary. If we had continued with HTML we would have eventually hit a block past which it would be too difficult to continue to create on it without introducing more bugs due to various limitations. So rather than having to force everyone to switch after a year of updates, we thought it was better to do it now even if it's still difficult in some ways.
I have noted all the frustrations and issues listed by people here but some of them could have been solved by just reading the release notes in the changelog or the public post in our patreon. But I will try to address each concerns listed so far.
1)
Saves not working! or....I don't wanna start from the beginning 
= Quick saves were provided in the downloads post in our patreon which was made public shortly before it released here. Also
MIRONENKO had kindly pasted the same saves here in case anyone wants to search for it in the thread. Make sure the folder location is right for them to work correctly.
Saves can be saved if you press the "Enter" key after typing in a name. This little mechanism will be made better to avoid future confusion but for now there should be no issues in saving a file like this. Unlike HTML, you can potentially have unlimited save files and also name them as you wish!

Why no android for a phone game? 
- Yeah we know it looks lame but we barely just shifted to Unity and didn't want to cause any more delays by waiting to make a android port. Most won't say it here but I know they wouldn't want more delays to wait for android. But do know that we are already working on making an android port and we will release it after we make sure it runs good enough.

Why not use Renpy duh? Unity sucks! 
- Yeah we know Renpy is the good ol' golden boy but for a game like ours, Renpy appears somewhat restricted and limited. I am sure those who work on Renpy might be able to relate. Of course you can brute force your way through to make most features Renpy doesn't provide but that's just too much extra development time while Unity can make it so much easier. We already have a long list of extra features we plan to implement to turn this game into a "phone" game. But trying to do them in Renpy wouldn't be worth the hassle and eventually yall would understand.
We have yet to focus on optimization but when it's done, trust us that Unity won't be so annoying.

2 months for each route? Nah, I will be in the grave by the time this game is finished 
- I have no idea where someone got this specific number from but we have never said such thing. In discord, I did say that we plan to use 1 month for Cuck Route and 1 month for both Cheating and Loyal Routes. But tbh I think it might be better to do most games are doing - Run a poll and let people choose which route they want to see the most and focus on it. We already planned to do this earlier but first we wanted everyone to have a taste of all routes.
5)
Nothing happened in v0.5.0
- We did say this before but this game won't jump straight to sex, especially Cheating Route. NTR shines the most when it's slowburn. It's already been observed that ntr fans get bored quick if they see the woman getting loose quick. So while it's fun and entertaining at first, it gets old too quick if there is no build-up between the characters and without relying
only on the blackmail trope which would have made things a lot easier from a writer's pov.
But those who are only interested in hot scenes should keep a look out for the next release which will be for cuck route

I am confused which route to go and some choices just gets locked - To prevent this issue, please turn on "Hints" in the Settings app. And it would be better to not skip anything so that you can get an idea of the routes from the plot itself and without even needing hints.
The part where choices get locked first is where you enter Cuck, Cheating or Loyal route based on the previous choices. But each of these routes have multiple sub-routes and the choices you make there will eventually lead you to a fixed route with a specific ending.
Also please note that you may or may not see some scenes based on the route you are in.
And do note that Love Interests can only be skipped in the Cuck Route, specifically if you are an Alpha Cuck. Pretty sure I had mentioned this in the thread long ago.

Unable to go back from zoomed image or the arrow is hidden by dark backgrounds - Yeah this was a issue in the HTML version as well. Fortunately we have found the right solution and are working on implementing it

. In the meantime you can just keep pressing the place where you had seen the back arrow before and it will close. Yeah I know it's annoying and dumb but hopefully this issue shouldn't be there next time
So this post has been pretty long but I tried to address all the concerns I could remember reading here. Please lmk if I am missing something. I will try to address any genuine concerns.
