Really great game (and demo) overall, it kept me going for hours.
At first I was really missing the option of being able to somewhat aim my shots ( shooting upwards, or crouching to shoot lower), but as I got more comfortable with the mechanics, I'm not sure it's needed. Having to skillfully position yourself and utilizing the environment to land the hits ends up being pretty fun.
Great enemy variation, amazing visuals, clean sound design, responsive and tight controls... honestly, this game has it all.
Best of luck and I can't wait to play it when it's finished !!
Extra points for the chuckle I had with the shopkeeper dialog.
