This was weirdly addictive, it's a great package altogether! I love the unconventional inputs of using the numpad, it reminded me of typing games I had on cd rom as a kid. The only critique I have is for balance (which is literally impossible to get right in a jam, from my experience), and it's that I felt as though I got enough zeroes that I could just shoot the ones without worrying about the shield. Overall, a great game, nice work!
