Good idee but not expended enough. I mean you don't have anything that force you to change mid game your gun scale. You just do 2-3 test to see which type you want to play with and that's it . I would have love different enemy who need a certain gun size to be defeated ! Like the damage affecting your speed so some fast enemy can't be deal with a max damage gun and slow one with armor that can't be damage with low damage output. and so on...
There is some bug with the AI you just have to be far from the middle and they bug out stopping to attack :
