Hey! Thanks for the review :)
Originally it was the one of the first idea that I have to add 1,2,3 keys to switch between weapons. Or with mouse wheel. But in that case game could be much siplier I had to add some extra complexity on it. And I had no idea which coplexity to add :D So I sticked up with buttons.
But seems you have mentioned that, I think now that it comes naturally and should be implemented , so I will work on that later.
Gonna play your game !:)
