Thank you very much for testing our game. Feedback like yours is really important to us.
From your video I’ve already spotted a few issues that work fine on our systems but didn’t on yours, so I can start fixing them right away.
Just a small tip: if you want to shoot, try aiming with the right mouse button first. That way you can rotate the character toward the direction you want to fire. If you only shoot with the left mouse button, it becomes much more difficult. :) ty
