I personally played only the famous or well known visual novels so far and it usually comes in two more distinct types of gameplay. One is that it's much more railroaded which is the more simpler type of visual novels and the other is much more free form which is much more harder to do, as I have not much experience making one, we decided to do the simpler option. However, they are much more longer in game length compare to our game.
I would take that as a compliment on the good part of the game :). Though my attempt on making the game bad was the writing, especially with the ending. It's a play on deus ex machina and Hollywood kind of movies where sometimes without explanation the main character and his sidekick still manage to be safe.
Overall thank you for the comment, and I do still hope you enjoyed our game!
