Hello everyone!
Yesterday I pushed an update for the demo of the game that addresses a lot of the issues with the gamepad controls.
Using the right stick is still possible, but now you can just use (X)/(square) by default on your gamepad to throw the boomerang in front of you, and angle upwards or downwards with up/down. I also cranked the aim assist up to eleven. From testing it works pretty well, and since a lot of people suggested aiming with the movement buttons to begin with, I hope this solves most of the issues.
Also, if you've already played the demo I suggest going to the controls options and click on the restore defaults button to avoid confusion.
I've also added a disclaimer at the start that low-key recommends keyboard and mouse, because these changes make the game way easier with controller. That being said, if you want a more casual experience, controller is likely the way to go.
It's on my to-do to add an invert-sprint option as well.
Thanks to everybody for your patience, have a nice day!
