The sound effect of the tip pop-up became grating. CTRL wasn't a great keybind for me as CTRL+A/S/D/W triggered functions on my browser. Though, I liked the whimsical feel of the game.
Thanks for the feedback. It is very good information for future reference. I used unitys default settings for Fire1 and Horizontal input so you can use ad or arrows to move also you could shoot with the mouse or I added numpad 0 but the information you have provided is super valuable so thanks!
