First of all, I like how the game is made with Godot. The concept of the game is very creative. I did get want I am going to do at first, but once I understood it is really fun. The level design is also really good, the learning curve is just right, and there are many pretty challenging levels after getting to two digits.
If you have time, please take a look at my game. It is also a puzzle game made with godot.
