It is probably less about speed and more about responsiveness. Some instant audio/visual feedback on hover and click before the animations play might help. They are there for text-decisions, but lack when interacting with world elements sometimes (this might be lag due to browser play tho!)
Furthermore, some of the animation curves for elements that slide into the screen seem very linear, adjusting them into a more eccentric ease might add to their character and improve game feel.
One minor thing, comparing the textboxes to that of citizen sleeper or disco elysium, when too little text to fill the entire texbox is displayed, it still alings to the bottom. The decision/continue button is thus always at the same position.
I think immedeately flooring the text-scroll when new parts appear instead of making it adjust smoothly could also add to a better reading experience, as right now it is a bit disorienting.
Good call on double-checking all the interactions for sound queues. They're *supposed* to have them, but in the midst of all the different things to do some might have gotten lost. Will check them all today!
Thanks again for the details, added them to my to-do list before I start sending this out to publishers :D
