Thanks for the insights ! I am no coder, so I may sound dumb, but the dream control scheme to me would be : press B + direction to strafe, and use the crank to swap weapons, as it does not happen that often. It would be a great way to make the game more dynamic and to celebrate the uniqueness of the Playdate, but maybe it is too complicated to code ?
I would be very excited by new ennemies, weapons or themes. There is so much to create with the awesome game you made !
