Yoooo, wow so good! I really want to see it complete.
I'm so impressed by this game. The gameplay is good, the concept is good, the challenge in this demo is well-thought out.
As Xziled pointed out in the comment below, the controls could be more ergonomic. Since we're using WASD and the mouse, then why not use all of the mouse? You could easily get away with Dash on the right click, Lock-on on the middle click, Focus on Space and "weapon" selection with the scrollwheel.
Well yeah, speaking of Focus, I didn't use it much if not at all because I feel like pressing Shift while using WASD to move is awkward.
Despite of these small details, it's a really amazing and promising small demo, looking forward for more. I featured this game in my video here:
