This was cool, it reminded me of "Brain it On!" on android, a game I liked. I also like the sound and visuals of the game. I got kinda frustrated from fiddling with the physics, I didn't get very far past the tutorial. The tutorial in particular was really good, I very easily understood what tools I had at my disposal and how to use them. But I really liked seeing what kinds of things you did with Godot. I didn't know I could make a game automatically launch to fullscreen! Also I wanna guess you used the _draw() function for a lot of the graphics because they're minimalist (and really good looking, you really polished the game well). I definitely would have gone that direction too if I didn't want a dog in my game. Regardless this is a cool game idea, I just wish I got to use my brain more and my patience less!
Oh, and I'd love to hear your honest thoughts on my game too, if you have time!
