It was my first successful attempt. The game is very difficult, because you have only one life and 200 hp with no ability to replenish it with some health kits. So you will die and restart much. Last level I had 5 hp on last few monsters and it was very nervous :)

In the middle of the game after Level 6 at time 11m 58s (12:50) my DOSBox became frozen and I couldn't fix this. So I closed application and run it again. Then I used a code for Level 7 and continued at 17m 1s (17:52). Game progress doesn't save any useful things (such as hp, or ammo) so I subtracted 6m 3s from resulted time. LiveSplit was running all the time during my run with total time of 1h 4m 29s and speedrun time is 58m 26s.

I will definitely try to beat this time, but it's not bad for the first time :)
