Not bad at all, took me a moment to realize the puzzle is literally godot's coding language and after that it was smooth sailing minus the last level, using the vars and if statements like that is really cool and quite creative, this is one of the few times I don't think the lack of music hurts the game, making it absent makes it more focused on the bomb, not saying it wouldn't help either but I am fine with no music to listen to. Good stuff!
