Stylish game. It's a very interesting idea and I love how the aesthetics matches with the idea.
But I find it really difficult to understand exactly how the shooting mechanics work. Every time I let go there is a blue circle, I suppose that's where the explosions happen. But sometimes it does not kill the enemy ships. Sometimes the reticle starts firing frequently and I can't figure out why. Sometimes there are yellow ships spawning that seem friendly, but I have no clue what they do or if I can control them somehow.
I still think it's a very creative and stylish take on the theme and I think the game would be very nice to play on a touch pad. With some clearer instructions and slower difficulty ramping I think the game will be a lot more enjoyable!
