@DragonFire If you won't mind, I will respond to your suggestions.
1) Being able to name the saves - this would be helpful, but I am almost certain it would require quite a few changes in the code. If there ever is a remake of this game, I am sure we will look into this option. I personally use different pages for different girls (e.g. page 5 for Helga, page 8 for Alanna etc.) and this definitely helps with keeping some order in the saves.
2) Walkthrough - I agree with you that this could be done little bit better, but this game is quite linear, and the only walkthrough you really need, is to stick with the rule "don't be a dick to the girl you want to end up with". Yes, there is one situation where the player has no idea about consequences of his decision, but that's about it. However, I did think for quite some time about making changes to the walkthrough, so maybe I will finally get to them.
3) Save compatibility - Novel never wants to break old saves, but this sadly happens from time to time. If you want to use your old saves as often as possible, then do not play version which is released here first, it is the version for 10$ patrons and it does not have to be bug-free. Play the public release, which has been played/tested by many players, and most likely is as close to bug-free as we will ever get with that particular update.
On a final note, constructive criticism is always welcomed, it helps make the game better and more enjoyable. Sadly, google translate cannot always convey your message in exactly the way you want or intend to, so mistakes can happen. I hope you have a good day and maybe one day you will return to this game.
