I think it is a $10 game.
The trouble is that a lot of $2 games aren't $2 games - they are probably easily $5 games.
Put it this way - how much time would you expect to spend playing it?
Suppose you spend even just 10 hours in total playing it - $1 an hour of entertainment.
You're telling me that $1 per hour of entertainment is too expensive?
It comes down to the fact you can find $0, $0.5 or $0.1 per hour entertainment at the same, or better quality gameplay, than this game. You are paying a lot for just the name/branding of the game, which is fine if not for the fact, the game doesn't live up to the quality of game you expect for that brand. A direct port of a 20 year old game would probably have been more fun than this game.
