I had fun playing your game.
Graphics are simple, however they all fit nicely together. The transition between screens felt very smooth and responsive - I found it satisfying to just rapidly switch between them while waiting for a warning to popup ;)
I think you did a very good job of communicating information to the player in general, and making the minigames intuitive to understand.
For improvements, I unfortunately could not complete the game due to the asteroids task bugging out during the final phase. I'd recommend ramping up the difficulty of the minigames over time; an extra button/bar added to each task here and there. Also, I got the same task 3 times in a row at one point, maybe code it so you can't repeat a task.
Overall, quite a simple and yet polished, well executed, and fun game. Great job!
