Amazing little project! Scaring off as many people as you can is really satisfying damn, that doesn't sound so good... once you meet all of them and learn their "weak spots". The short run time makes it very replayable and enjoyable: you can try to beat that high score of yours as much as you want, you won't snap out of it several hours later after only a few attempts!
Overral, great game!
Keep up the good work!
