Tougher than I expected! I like the structure of the game, never gets too frustrating even if it requires some trial and error at times. Great presentation, too.
For some reason the game won't recognize some inputs from an Xbox One controller. It recognizes XYBA and the L/R bumpers, along with the two menu buttons, but not the sticks, D-pad or triggers.
edit: Nevermind, analog sticks seem to work. Not the d-pad or triggers, though.
