I really liked it! It starts nice and easy, but as the speed of the enemies ramps up, so does the tension. It felt really cool to first miss, acrobat your way around the enemies, pick the shuriken back up and land a sweet double kill mid-air. For being made in a day, it felt really well thought-out and neat. If you plan on updating it sometime, improving the player feedback could make it excel (although I already admire the fact that you implemented screenshake when landing a shot, it adds a lot). All together, a really well-done jam entry!
