Atmospheric little game with great soundtrack and tank controls. I'll always have a soft spot for it. The difficulty abruptly spikes a few levels in and the game kind of rapidly concludes itself after that, leading me to believe that maybe they ran out of time or budget and had to wrap things up, to this day I have no idea. Still a lot of fun to play, though, even if the last actual "level" might test your patience, it is a fun journey. Love recommending this to people only to watch them stream themselves get mercilessly filtered by stage 4.
