I like the concept but the progression feels way too slow. The bot intelligence is pretty frustrating and upgrading it seems extremely slow to where I can't really tell that it's improving. I also feel like the money earned is slow, maybe they're the same problem since the bots are bad at earning when they are bad at playing. It would be a really neat idea if the progression was sped up quite a lot.

I'm analyzing this probably more seriously than is needed but...if you wanna make it better, there should be a way to gauge depth because the black background makes it hard. Also I suggest maybe a mouse control option for more precision than WASD.
