Frankly I’m a bit baffled about why you would release a game in this stage of development as a “full release”. If you like the top-down shooter genre, here is my recommendation for you: Follow this game on Steam and check for updates they might release, then get the undeniable indie-king of the genre: Running With Rifles.

Gunnheim is almost a torture to play because of its awful combat mechanics.

But in the end, the only scenario where I might recommend this game to others is one in which you and your friends are looking for a light, mindless game to complete in an hour or two and never play again. And even then I would be cautious, as there are plenty of other twin stick shooters out there that are far more enjoyable than Gunnheim.
