Is there a way to play with with a touchpad?

[Contrast]

I normally use my laptop to play games and I don't have a mouse. To use the harpoon, I have to aim with right click and shoot with a left click, but I can't do that on a laptop touchpad. Is there a way to get around this? Or do I just have to buy a mouse?

You can remap the buttons, could probably use arrow keys and WASD if you want instead of mouse buttons. I haven't used a touchpad in 20 years so I cant speak to how useful it is.

Remap or use a mouse. Touchpads (and the old eraserhead mice in the keyboard) annoy the heck out of me, personally.

TBH, this game feels like it'd be better with a controller over the keyboard and mouse.
