Congrats on your submission! I couldn't upgrade my ammo box anymore and it was getting very hard to see the units after there were so many bodies everywhere. I had over $4K and my ammo box would not upgrade, the cost was $3.8K. I wasn't sure if the game ended and I had over a 20K score, so I quit the game. Leaderboard touch is nice. I liked the music and the blood effects when shooting the enemies.
