I find the Story interesting and want to know more. you did go overboard with the text effects. Im a fast reader and this stuff distracts me from the story massively. When you make text gradually appear like the Speech from the Headmaster it renders the Text from the beginning every time you click so i reread text trice because i thought it would be something new.
To be honest the moment you talked about Sandbox mechanics i nearly deleted the game. Sandbox only breaks the flow and brings nothing to the game. I really hope you make a VN mode it would be a shame to drop this game.
also your free roam nightmare is bugged when you first explore the ground floor before you enter the room you can go back and if you go forward again the same event gets triggered you can repeat this indefinitely.
Edit: also major gripe that you cant rename the main Character that's something the overwhelming majority of AVN players feel strongly about
Ill make sure to take another look at the headmasters text effects. I did try to tone it down after realising how buggy they are xD
As for the sandbox, it wont be a large part of the game. The story will be mostly linear, with a large string of events in the middle. The sandbox is mainly for people to choose which characters they wish to spend more time with. However i plan to set it up very linear(such as talk to Iriella, then the story progresses), so that the objective is always clear. The games branching stories largely relies on your choices in certain scenes, not character affection or events. Id love to hear your thoughts or reccomendations on it, as its a system im currently developing.
The free roam nightmare is a testing variable i forgot to change so ill go ahead and change it now for the mext update xD
And as for the name, that was a huge gripe for me as well, while developing the game. There is a way for you to insert a name or rather nickname, for lucerus in the next update. It wont replace his name but works more like a title that everyone will call him, without spoiling too much.
Im glad you enjoyed the story so far!
