I haven't done much so far (blame SGDQ and Pokémon GO, as well as saving energy for the GM48 gamejam this weekend), but here's what I have on my game so far. As a reminder, I'm doing Dungeon of Flowers.
It's really just the movement system that's complete. You can use mouse/keyboard or a gamepad, it's the usual twinstick-type movement. When using a gamepad, left stick moves and right stick aims. If you let go of right stick for 2 seconds, then aim just follows left stick's movement.
Now it's time for some animations and background tiles!
