This is actualy good constructive feedback thank you.
Firstly the clown was inspired by 'IT'
Secondly we do plan to impliment a tutorial level to slowly explain the mecahnics.
We do plan to release with the initial basic level of simply catching the catching the ghost and draging them to the traps. The roulette parts we plan to impliment as add on weapon types or a variant scene or chapter that can be unlocked. (note it was originaly meant to be 1 trap 1 ghost)
As for the rotating gun we combined ghostbusters with the ripper ribbit arcade game, we are still collecting feedback on weather to change this mechanic or not but for the most part most people enjoy the mecahnic.
Again thank you for your constructive feedback
