The game is pretty fun, and the sound effects very satisfying, the art style is great and I love how the final boss is just your profile picture, but the controls are really annoying, because you always move towards the cursor, it was hard to aim towards an enemy without also moving towards it, I know if you put your cursor really close to your player, it doesn't do that, but that's really finicky, so maybe you should have just gone with just wasd movement and shoot with left click and block with right click? Also there's way too little feedback when hitting an enemy, taking damage and killing and enemy, you should add camera shake, at that makes everything better, particles, like enemy dead and damaged, and maybe a red flash of the screen when getting damaged yourself, also the missiles should have explosion particles on contact, and getting an upgrade is way too unsatisfying, there should be a ton of particles and the upgrades should come to the screen much more slowly, as now they have a really fast animation, but it's not really that satisfying, also you should add an animation for when the upgrade screen goes away, and when you have maxed out an upgrade, there should be a text or something that says maxed, as now you are left wondering for a while, that why can't I buy this upgrade any more. Also why are the upgrades appear and death sound effect some meme sounds, it's just weird. Then also you should add something else in the background, other than just a plain color, it's really boring currently. Aaand now that I gave you tons of feedback, you are legally obligated to play our game on your stream, as playing your game was apperently a requirement for that :)...
