Being bad at fighting Spirella for 3 minutes

Fun fact, I did not have nor did I know the grapple upgrade existed when I did this boss. To access the bottom bit of lab, I did a shotgun jump into a grapple, exploded a grenade to get a bit of height and shotgun into a regrapple, then shotgunned again to get the ledgegrab (I did not know rocket jumps were a thing).
Honestly I have no idea if I was underequipped for this fight (as far as a first playthrough goes). I do think this fight probably benefits from being upgradeless (a lot of the lategame bosses felt quite trivial with level 3-4 weapons).
I really do love how this game just lets you do stuff in whatever order. Very cool.
