Poor.
Your parodies of classic games aren't good enough. Breakout isn't finished until every block is broken, Space invaders move faster the less there are of them & the control scheme for that was terrible. Generally the games flicked through so quickly that I spent more time learning the timings & controls than I did playing the game. Sketchbook graphics aren't my favourite but I'll admit they were done fairly well.
Overall why does pacman spend so long in a UFO & not imitating his own game?
