Hey! I've tried your game, just spent a short time figuring out the controls. I suggest you update the page with the baisc instructions for gameplay for the others who play it :P
In general, I liked the idea, the graphics and soundtrack! It's addicting and it's been a while since a played something of its genre. I look forward to any future updates you might have for your game :)
In case you wanna taste a vaporwave space shooter, feel free to take a look at my project as well!
Cheers ;)
