Not everything needs to be a romance. If you’re tagging a VN where romance isn’t the primary appeal with BxG, GxB, etc. — stop it, you stupid idiot.
Bloated download sizes
Specifically downloads that are only large because the creator fucked up. Uncompressed .wav audio, 40MB PSD files accidentally included, etc. I don’t think stock background music needs to be included at the full 320kb/s either…
Terrible dating sims
Stop it, you’re not talented enough. Making a good sim game is really hard and requires lots of events/minigames to break up the monotonous soul-evaporatingly boring stat grinding. Stat grinding by itself is not fun, there needs to be a goal, there needs to be strategy.
No continue indicator
There needs to be some kind of visual indicator to show when the text has fully appeared.
"Keep your images under 1024 pixels" — why? It’s also strangely common to see people talking about DPI. Protip: DPI DOES FUCKING NOTHING — it’s a hint for the default print size, that’s it.
Please, no more. Have mercy. Contrary to popular belief, there are other sources of creative commons music.
Shitty flash engines
Especially the ones lacking save and keyboard support. What kind of lunatic makes a visual novel where only mouse clicks on the text box continue the text.
"Visual novel game"
Visual novel or game, pick one. Don’t propagate the erroneous belief that visual novels should/will contain gameplay.
Ren’Py has an ImageDissolve function y’know. It adds variety — use it.
Not reading translated VNs
This is disturbingly common.
