Fun game! I think you did a great job with this game! One recommendation I have is to use position smoothing for the camera. You're using Godot, so just click on the camera node, look for position smoothing, turn it on, and experiment with the numbers. Start with 7 and go between 3 and 15 (or higher/lower if you feel like it). It will make the camera movement follow the player smoothly, decreasing the vertigo feeling when you run around. Besides that you did a great job with the game. Great work!
