Id give more explainations of what things do, for example what do the things you spend research on do.
Id also change something about the bees, they are arguably the hardest enemy ive seen so far and are a large factor in the lack of viability of high damage low fire rate builds as you cant just use piercing and under barrel attatchments dont help much, i believe the main problem with them is that they first of all often hide behind the walls of the map making you unable to hit them and due to their circular movement it makes it hard to escape from
