The game is pretty short and can be completed in less than 10 minutes. It's still incredibly difficult, though, and will take longer if you want to get all the way through.
In addition to the gameplay, which is fun but quite hard, the best part of Streemerz 2 is the wild story. The game is full of winks to crazy characters from other games and some really great laughs.
If you're looking for a relatively short game (half an hour to an hour) that's also challenging and funny, Streemerz 2 is the perfect choice.
