This game rocks! The visuals, sound and gameplay are all great, I specially like the mine effect. The game is unbalanced as fuck sometimes (I got a round with like 8 enemies or so) but it makes it kinda fun.
When you enter the game the mouse doesn't get locked by default on browser. You have to full screen your browser for it to work properly. I don't know how Godot handles these things since I'm a Unity dev but it should be a couple of lines of code and some setting changes. The game ran perfectly on browser so congrats on that!
Oh yeah! One more thing. I would have loved a first level against just one enemy and no random modifiers to get a feel for the game and controls.
Other than that awesome game! And bonus points for being a beyblade game (us beyblade devs have to stick together)
