Hey, I like the game idea! For me it gets a bit too hard too fast, maybe slow down the pace a bit. For the task choice you used things where there is not much room for improvement. From a game development perspective you always want to have a learning curve on your game, as what makes a game fun is when you get better at it. Choose tasks where you are only able to solve them slowly, but get faster over time. Then add some stress-inducing music (maybe fast paced jazz) and you would have a full game! The graphics are great! Good job!
