Thanks for adding three weapons. You really know your FPS games, lol.
The fun of these game jams is that you can see ideas like combining a 3D visual novel with floating text and a shooter game come to life in just a week. I think this game is perfectly fine as-is without needing extra enemies. It's not like Destiny where you need different enemies each season to get better loot, right? I'm glad I didn't encounter the weapon bug mentioned in other comments! I genuinely enjoyed the shooting throughout the entire game.
