This game is really fun, but it's generally not a good game to play on a Mac/Chromebook or any device with a touchpad instead of a mouse.
It's not even the game's fault, it's just that aiming by holding down the left-click both makes your finger cramp and makes your aim choppy or just inaccurate. Trying to balance that and moving at a high-speed pace to dodge makes it super hard to play.
The game is a ten-out-of-ten, but I'm just sad I couldn't fully play it. Maybe add a different button to use your flashlight so you can both aim and shoot without it being annoying too? (F for flashlight maybe?)
