Hey, I beat it without any hints, nice! I fully understood what I had to do on the second run, but it took around five runs to figure out all the timings, which admittedly did get a bit tedious, especially the 2-3 minute wait between shields and the laser.
So I’d say the game has three critical things you need to know; the code to the locker, the time to shield and the time to laser. The problem I had though was that you can’t know the next thing until you’ve done the previous thing correctly, and once you know, then the window of opportunity has passed and you need to reset. So at the very minimum, you’d need three runs, one to see the time that you need to shield, reset, then one to use the shield then see the time to shoot, reset, then one to do it all. And all that takes around 10 minutes of mostly waiting, and I messed up once or twice adding to that.
I still really enjoyed the game, the vibe is awesome, and I particularly love the music! Thanks!
