Very basic Mario game. Not bad by any means but it didn't wow me.

Absurdly good, I’m kicking myself for not playing it earlier. It holds up amazingly and is just as good as everyone says it is, my only complaint is that it’s pretty short- took less than two hours to beat, but the puzzles were good, the jokes were good, the gameplay was intuitive, it was very engaging, and there’s still things to do outside the story. The glitches and quirks don’t impede gameplay at all and are fun to mess with. Really, I can’t say enough good things about Portal.
