Really cool game! The tutorial is cool although he's taking 2 minutes to say something he could've said in 2 seconds lol. I love the juicy UI animations, although some of them don't have sound effects. The UI is too big and blocks the player's vision quite often. The shop is buggy, sometimes items are invisible and sometimes it automatically buys something that you haven't clicked (I believe this happened when I refreshed the shop while the purchase animations were still going). Also, the boss attacks are pretty much impossible to avoid - the gap between the gigantic bullets only grows big enough for the player to pass through when they reach the corner of the map.
Tip for godot web builds: Show all your particles at the start of the game in the main menu (they can be hidden behind a colorrect or something). This gets rid of the freeze that otherwise happens mid-game when particles are shown for the first time.
Music is peak and your game page is the best one I've seen!
