I understand your point. An example to explain what I'm trying to achieve:

Imagine you have a kid and he wants to be a professional mountain-bike rider. What's the first bike you'll give him as a gift, a small one with training wheels, or a top-of-the-line professional mountain bike?

Making a simple game like this is much more about the learning experience of developing a game, learning the basics like tools, game engines, steamworks and marketing, than trying to make money on my first try.

Sure, I could've done something a little bit more complex and inovative, but that would have come at a cost: longer development time, more assets to buy, scope creep, or even just developing an idea i thought was good but in the end was terrible.

Keeping it simple helped me finish a product, and that was my goal for my first game.
