Polished in all domains: level design and mechanics, as well as visuals and sound. This really feels like some lost gem from 1993. Challenge level is tough but fair. Keeps you motivated to keep playing like the best old school games. Only con: imperfect 4:3 aspect ratio support, for those that want to play fullscreen on a typical CRT TV. Would be nice to have a "pan and scan" buttonso you could pan the game camera to the right to see all the objstacles ahead. If you really want to give it a go Instead of 320x240 @ 60hz, you can try a desktop resolution of 360x270 @ 55hz, which gets more screenspace on the right and left so you're less frequently fighting bad guys you can't see. I haven't played all levels yet, so there may be cases where running 16:9 424x240 or 480x270 is necessary
