Dear god go spend your money on something else!
The controls are so badly messed up that playing Pong was essentially impossible. So much for getting the unlocks there.
Having given up on unlocking the main reason I got the game, I thought I'd try one of my favorite arcade games, Tempest. The evolved version suffers from way too much blur to really tell what's going on. The flip screen is extra stupid and I found it easier to play with the screen in the normal position (so sideways for the way the game wants me to hold it). The regular version is okay, but the lack of speed with the controls pretty much ruined any sense of skill in this game.
The rest of the gameplay was so bad I've scrubbed the memory from my brain and gotten rid of the game itself.
If you've never played the arcade games and don't mind playing with painfully bad controls, and you were given a free copy of this game, you might not mind it. Instead you should probably go get any of the other nostalgia game collections as this is easily the worst of the lot.
