I appreciate your honest feedback. It's totally fair and I understand your frustration. Most people didn't seem to mind but I did get some feedback like yours after the initial release. I don't wanna go too much into technical details but while later versions of the RPG-Maker have a build in sprint option at default, older versions (like the one I used) did not have that. And instead of writing a new script to have that option in the game I decided to go the same route as the RPG-Maker games that I enjoyed myself and chose the same walking speed you have in those games. That being said the game ended up larger and with more exploration than I thought at the beginning so I get why some people find it frustrating. I did not add a sprint option in later versions because the game expects the character to have that certain speed and adding a new mechanic would require quite a lot of work... and time. And I'm simply not willing to spend even more months on a project that I offer for free and already took me way too many years to finish. Just to give you an explaination of why it's still the way it is even if some people already mentioned that. But I'm glad you were able to enjoy most of the game!
And I assure you if I ever make another one, I would go in a quite different direction and allow players to customize their playstyle.
(Including sprinting.) Thank you for taking the time to play it and leaving your thoughts!
