It's not what I had hoped for, but it's not bad. I programmed the moves for my gamepad, which definately made the game more enjoyable.
It's nowhere near as fun as the original 2D version (that game was AWESOME), but it was ok; and the nastalgic music playing during the config screens almost brought a tear of joy to my eyes. If I ever see it in the bargain bin, I'll probably pick it up.
While the controls were BETTER with the gamepad than the keyboard, they were far from perfect. I found it a pain to face my enemy, but actual combat (punching, kicking, combos) was alright. Force is a cool 'bot, and I easily beat Raven on more difficult settings.
All-in-all, I'd give the demo a 7 / 10. While it has some "issues", and nowhere comes close to the original version, it's an alright game that beings back memories of playing it on my old 486DX 33.
