This is really fun. The controls are a little difficult. But releasing a beast into the world is really cool and works out great.
Well what would have worked for me is if you could hold down the throw button without having it throw when the throw-power is maxed out. This way I have a moment to aim before it goes off. (Like most grenades in first person shooters.)
Oh and don't be afraid to make your game jam game to easy. (because If other people play it it will often turn out to be too hard for them.)
