Thx for the feedback! Those sound like really nice ideas that i will for sure add in the future. I wanted to add more features too but it was complicated because of my limited knowledge of the game engine and code.
Perhaps I could help you with that, but the thing is I use UNITY and I have no idea at Godot at the moment, also you can use ai for your code mechanics, so you can focus more on thinking ideas and drawing the sprites, you can check my game too if you want some ideas😉
