Wow you put quite a bit of effort into this! The game game is fun on it's own but when you added that shop system's powers, the game has changed for the better, the music used is really good and fits nicely in, that feeling of shooting an enemy and watching them shatter into a hundred pieces feels so good with that glass shattering sound effect put on top of it, you put quite a bit of content and polish in this game and I can see it, while I feel there is a bit too much bloom it isn't blinding amounts the html build's screen is a little too zoomed in so I couldn't read the power's text, honestly I would love to play this in the future if it ever gets expanded upon, pretty good stuff!
