Ease of use is crucial. If a tool has a complex interface or a difficult scripting language, it can be a big obstacle, especially for beginners. For example, TyranoBuilder's drag - and - drop interface makes it very accessible. Cost is another factor. Some tools like Ren'Py are free, which is great for those on a tight budget. Features also matter. Tools that offer character customization, branching storylines, and easy integration of multimedia elements like music and images are more desirable.
The level of customization the tool allows is a key consideration. Some tools may be more restrictive in terms of how you can design your characters, scenes, or the overall look of the visual novel. Tools like Visual Novel Maker, which offer a wide range of customization options, can be very appealing. Another factor is the tool's performance. If it lags or has glitches when handling larger projects or more complex elements, it can be a problem. You want a tool that can handle your creative vision smoothly.
