so i grew up with an atari 2600, so other than figuring out how the "asteroids/astroblast" game was not quite either asteroids OR astroblast, these were challenges i could breeze through.
They then got repeaty. Being repeaty is a tricky thing. My own game is repeaty, but my game is grindy, where being repeaty is acceptable.
Making more minigames, which i expect would have been impossible in the time allotted, would be best for making a more finished game where the challenges did not get stale.
