Pretty good game you put together in a short time. Ran into a couple quirks though: I wasn't able to see the UI (it was scaled off screen) but eventually figured out that Q and W were the special. Oh and it wasn't clear what the sword and ... toilet paper roll? icons were for when you beat the level. Some popover hints would help out with that.
But overall, good job especially since you did it solo! Check out our game too if you get the chance.
