On top of what Stevie mentioned - I recommend checking out the game's itch page! Demon's Fortune by Shoniver, Stevie :D
I mentioned this in other comments, but we basically just ran out of time and couldn't communicate things in-game properly, so we made sure to write the controls and stuff on the website - including the quick-transfer behavior, which is indeed implemented :D
Either way - thanks again for the feedback! :D
