It's a game thought for playing just for a little and we didn't expect to reach much more than 4,000 points, the amount you need to unblock the last one of the critters, so yes, once you surpass this number it gets really crazy. Our highest punctuation is like 7,200 or so, and doing like you, spamming the shoot and jump buttons at the end.
Thank you very much for playing, for your words and for your feedback!
