I LOVE THIS! Maybe it's because my game also has convoluted controls, but this was a really enjoyable test of my dexterity. That first moment where you had to jump then shoot the dude in midair felt so good to pull off! Your decision to allow the key combos to be used on the button press and not the initial combination is a fantastic piece of game design, really shows how much thought you put into the main mechanic. I enjoyed the level art (not so much the UI), your color pallet helps tie everything together and your consistent pixel size helps to make everything feel cohesive.
