I played Dogfight on a 486SX/25 mHz back in the day, it was super smooth and in no way as choppy as this port is. Steering left/right is imprecise and instead of a smooth steering we get choppy controls, as if the game was running with a reduced framerate. The game is unplayable as it is now as it feels like being played on a 386SX PC with 1 MB of RAM that could barely run the game. Btw: use CTRL+Q to exit the game. I think that this port should be rebalanced since it does not provide the same playability as the orignial MS DOS version.
The game is a classic in the sense that any PC gamer who started out on a 286/386 PC in the 1990s will be overly sentimental about how good this game is, well the game - as a platformer - is not immersive, the sounds and music are not jaw-dropping but it's a nice little retro game you can play on a Friday night and reminisce how good those old days were.
