Hello! Thanks for trying out the game, I'm sorry to hear you are experiencing issues with running it. I haven't heard anyone mention similar problems, is it possible for you to try it in another browser and see if it works better?
I had tried 2 different browser before remembering windows comes with Edge now. And it worked perfectly on that!
For my thoughts on the game: It looks beautiful, I love the background glitch effect especially. Movement felt good if a little fast. Creative enemy type with the laser, altho I found it weird your weapon doesnt damage it (atleast, I don't think so??). Rated now.
