I played about 1h of the Aeromachina demo, I suppose it's all right, but it just doesn't do anything interesting that sets it apart. It's just a 3rd person metroidvania, which admittedly isn't that common, but the systems are all fairly rigid and prescriptive. if you're just looking for content then it'll probably do you fine, but I'm always looking for interesting ideas.

5.5/10 for me
