Great! I can’t wait for that. I definitely want to try it when it’s updated because I was having so much fun. And I can’t hope to enjoy just as much the remaining of the game.
Personally I think to throw out the cup F is easy to reach, just like D. F has the little bump dot and it’s close to the spacebar and it doesn’t need much acrobatics.
Shift is not as comfortable as those but would be slightly better than Ctrl (in that case I’d put Help in H, which is also a standard help button).
But I will try Ctrl just like you said!
