not bad
The background isn't very realistic.The sound could be made richer.
The frogs are very original.
For thouse who say this game is hard,they are wrong.
It's all a matter of geting used to it.
All you have to do is get the special suit at the begining of the game(it's near your ship) and the frogs are no longer a threat to you.
You can gain lives by defeating opponents.You don't have to fight every opponent,just run when you've had enough.
The instructions you get during the game are very helpfull.The final battle with the frog king is funy.
I just finished the game with 7 lives.
All in all it's a good game.Not great,but good.
