This game. I love it. I have been having just the most fun I've had in a long while. I do have some complaints, like the lack of Auto Map or Auto Aim, which can help. But It's not too much of a problem with the level design.
It's all a really great package that really leaves me craving more. I would absolutely love to see a sequel to this. Or even better, a unique stand alone title that uses this Engine to build it. And if it fixes the issues I've mentioned, I will definitely be getting that, even if I have to pay for it. I'm looking forward to see what you create in the future.
