Pester is a Indie, Shoot 'Em Up, Bullet Hell PC game, developed by Flump Studios, available on Steam and published by Funbox Media Ltd.
A blast from Flump Studios past! Pester was released on Xbox live indies back in early 2013 and was Flump Studios first game developed for public release. A remake of one of my early C64 games, Pester is a very fast paced and busy retro vertical shooter.
