Hello! I really like the concept of this game, and it was quite fun(albeit grindy) to play through a few levels. I Like the gameplay and the graphics aren't bad. One suggestion, if I can, I would love it if you could add a "sandbox mode" where you can just play around with unlimited money and learn how to get good at the game. It won't be very hard to implement, considering those debug tools are already in the game. You can reuse a lot of things from the code of the debug tools for it.
Thanks!
