Played on original real hardware. I can improve this for quite a bit but was solid for a first run completed.

Mod Cybergeddon: Greetings friend from Brazil. Your official time is 44:30 not 44:39 that was your last hit.

Recommendations: At the last alien attack it easier with the weak or normal laser since if it can pass you to dodge your blows then you also dodge its melee blow and move away to position yourself for the next attack. You can improve your time and I am sure you can.
