Awesome-looking game! I'm glad to have been able to play this, this is a straight-forward, but nevertheless stunning game!
The gameplay concept is very simple and was a little bit irritating to me, since my aim of fire always faced the direction that I was going towards, so it ended up in me having to always distance myself from the enemies and come back, which I at first didn't like, but then I got used to it and realized that it really adds some uniqueness to the game and requires you to think a little bit ahead on how you're going to move and when.
I also really like the different powers you have, they all have cool-looking glows and I like how they each have unique abilities! I liked the freeze, it felt satisfying shooting the enemies with that and it made it easier on me when they were moving in slow-mo.
Overall, really nice demo to your game! I've seen many games with a reminiscent style to this one (dark environment, cute, little main character, colorful lights) but this felt like a really special experience! ;^)
