Thanks. I actually intended the dialogue system to be used for an over-lapping Jam that was Visual Novel themed, so that's why it got quite a bit of attention. Not sure if I'll have time for it now with rating and such. (Maybe a short one.)
Can I ask what you found tricky about the controls specifically? I assume it was the Keyboard ones. I noticed most games so far use WASD, while I favoured the directional buttons and Z-X-C-SpaceBar.
