Op, you did a good job. As you mentioned, there is room for improvement. I watched your YouTube trailer and I proceeded to download your game. I played for some minutes. Here is my brief review.
1. You paid so much attention to sound and graphics instead of progression of the game and simplicity.
2. There was no clear rule of each stage. I was lost at some point, especially when I got a new ATM.
At this point in this image, I didn't know if I was the one playing or the game was on autopilot.

How about if you introduce simple bitcoin quizzes so that when a player fails a stage, they can take a simple quiz, if they pass, they proceed from there and not repeat the stage.
I love simple games, I suspected it will be large when my mobile phone was turned to landscape orientation by the game.
I gave you merit.
Meanwhile, I had a horrible experience when I wanted to exit the game, I could not for almost 5 mins until I had to reboot my phone.
