It's above 101 points, and yes it's luck! (point 101 is the fastest and most difficult of those still playable) I've tried ultra reaction concentration, after 101 points maybe it's impossible. However, we can manage to optimise luck, depending on movements, shots (mouse + keyboard sidebar) and intuitions.

Thanks, Lio. I thought so..indeed after 101 there's was a shift from 'very difficult' to 'impossible'. I guess the best thing one can do is stock as many lives as possible in order to survive for a while above 101!
Leaving that aside, if you'd told me at the beginning of this month that I would score 101 in this game, I wouldn't believe you. It's amazing what one can do with practice.

That's right! first concentrate as hard as you can until you get to 101, then improve several techniques to optimize Kills. Yes practice is the key =) Congratulations for your 101 Stelios!! 😃

Great job guys! You are all awesome, I feel like 90s start to be really really difficult but once you hit 100 you should be a superhero, practice is all we have!
