Great game! Very good mehcanics. Here are some suggestions:
- Try to avoid having green shots flying towards player. Because it can be confused with bullets and adds clutter to the screen. Make them item pickups instead.
- Typing the words should add bullets instantly
- A proper tutorial that slowly introduces mechanics to the player wave by wave
- Player shouldn't have to type each word one by one to navigate the menu. Just have a tutorial where the player has to type something to initialize and leave the menu navigation to just mouse/arrow keys
