According to info, "Zarathrusta is classic European arcade fare that will keep you hunched over your joystick for weeks on end". Editor Tom Malcolm felt that the presentation was "top-notch", praising the game's sound effects and graphics, especially the backgrounds which "are animated and have that beautifully drawn, hard-edged European look". He noted that "the only real problem with the game is that learning to control your space ship is going to take some practice", explaining that "control requires a great deal of precision, so don't be discouraged if it takes a while to get the hang of it; your persistence will be amply rewarded". He awarded the game a score of 4 out of 5 describing Zarathrusta as "a very fine addition to your arcade collection".
