auto research does nothing to me... in my opinion you should remove clicking money at all and only get money when you click the special tings but then far more! so you wont be punished when you dont youse an auto clicker
it's ok but its kind of boring. Sometimes you cant see bullets, items drop on spikes, later on it is not even possible to dodge all bullets. Boss fight is easier than normal enemies
I'm thinking about it for the next game ;)
