Thanks for playing! 

Other people have said a similar thing about the clicking fatigue, it might be interesting to try an auto-shoot on cooldown method for the basic attack. I think if we did it would be nice to also add an SFX to the shot for some feedback. 

Middle-click to collect the gibs is kinda like a little mini game. It isn't necessary for the core game loop but playing around with the physics of them is fun; I believe allowing an auto-collect would take away some of the personality of the game. 

Again, thanks for playing and thanks for your feedback!
