It's fun and engaging, with a campaign mode that is quite challenging and a decent replayability thanks to unlockables, different maluses and objectives. It could need a lot of polishing if I'm being honest, for example a better HUD and better hitboxes.
It's a pretty amazing game and very addictive. The only issue with it is its short (and unforgettable) story and controls can become a bit clunky sometimes. But overall, for a game that started with one dev and then was finished with a small studio, it's an amazing 2 hours experience.
