Something that might help for the grammar and spelling mistakes is having one or two proofreader, preferably people who's first language is English (for the english version at least).
Anyways, is there going to be a Discordserver for the game?
I played v1.2, Things I meant are for example something like very early on
"So, Lussuria Academy huh, I'll [...]"
Where something like
"So Lussuria academy, Huh?
I'll [...]"
Feels a lot more intuitive to me for example.
Also "Great i have to mean the principal." should be "Great, I [...]"
In the Cafeteria the food appers from "tin air" instead of from "thin air"
Over all there are a lot of small "I" and "I'm' and such
I am very much looking forward to the new releases! Is the game going to be a pure VN or will it have Sandbox parts?
