Level 2 done. I'm quite happy with how it turned out in terms of speed, as in I had to wait a lot less for moving platforms than I feared that I might. Not too much to say about the boss battle, except that all missed half shots where missed because avoiding to do so would take time, and there are not that many either. And besides that, it all went smooth.
Now on the choice of weapons. I thought about this for some time and tested some stuff, and came to the conclusion that the machine gun and the crush missiles would be the best picks. Laser would have been faster on the boss because he is so big that he get hit 4 times per shot, but it would be slower on the smaller enemies before the boss, and in level 3 as well. I think that the flamethrower would have been slightly faster overall on the boss and the enemies before him, but only by a small amount, and upgrading it would make me waste some frames picking it up, and it is also completely worthless on level 3. Crush was collected since it is pretty important to have in level 3, where it speeds up things a lot, but the machine gun will still be faster in some places, which is the main point that makes it a better pick than the flamethrower.

The missing white space on the screen becomes pretty annoying here since most of the level is vertical scrolling, but I don't know how to keep it in there when recording.
