Yes it can be beaten, but the game works around the concept of repeating your run getting faster each time and thus progressing further. There are also more viable paths that will get you further, eventually though any path is viable.
if I were you, I would wait and see if it gets another update. As it is now, the current version doesn't have an ending. You just reach a point where you are so fast that run out of tasks.
Its just not worth it right now, and it doesn't seem like another update is coming
yeah. I also am building a little game and decided to use Godot to built it. The main code is in python so it works pretty well. Not too steep of a learning curve.
