Summary: Giving Retrovirus an 8. A beautiful love letter to a classic game that exists in an untouched genre until now. It's an absolute blast to play, and lasts surprisingly longer than I had expected it to, honestly. First play through took about 10 hours.
Summary: If you're like me and have been itching for a good Descent-like game, then this should satisfy you. Unlike the other user reviewers, I never had any crashes. There are a couple places where the difficulty spikes a bit high, and I had to resort to cheap tactics to continue.
Summary: I had given this game an 8. But it's just too unstable (even after a slew of updates). Couple crashing with save points that are a bit far between and too many stages that are just kill X number of enemies before continuing and you have game that becomes tedious.
Summary: Cool concept. A little bit buggy though. Only been playing for an hour and already got stuck in a tube with an observer that refused to move forcing a restart. On more than a few occasions I get pushed through or can clip through walls. Overall the difficulty is pretty good.
Summary: A very nice little game- it plays very well, has a beautiful environment, and is absolutely full of awful computer jokes and puns, as well as quite a few less specific jokes, mainly found in the spam emails.
