Adding some more good points:
- This would be a minmax TAS, which is kinda unusual (normally TASes only care about the "max" part)
- Under normal mode, there's a point where it takes longer to kill the boss than it rewards you with time, so the game eventually ends forcefully.
- Customisable difficulty - we could make the time rewards extra short for added FUN.
- The ship's shot type is a little weird: the default shot does slight more damage than the aimed shot, and moving while firing the default shot makes it more concentrated, dealing much more damage (and making the next boss become much stronger).
Now, I can think three categories for this game... "Reaches farthest level" and "Survives the longest" which are the most obvious, and the intended "100%" of the game - "Fastest unlock of all bosses"
For those who don't know, the boss can only take through customised forms of
these 13 "skeletons". Some work would have to be put on finding out what exactly triggers each evolution.
