Found the Wave Beam - it was exactly where I thought it was and I'm kicking myself for not noticing the slightly higher entrance rather than only the lower exit. Went back to fight
. Still got my ass kicked. Feel like this is bad design at this point - you can't possibly dodge the bullet hell attacks in the air, so you get forced to the ground, where you can't attack or even see your opponent. You can only go after it if it uses the green lazer or missile attacks, because all the rest make the aerial ascent too damaging, and often by the time you get there it goes back to bullet hell again. The save room is so far away the entire affair is rather tedious. Definitely the low point of the game for me.
had my number for a while until I got
, but I don't feel like I'm missing much now - I have no white circles left to go get items from, only dots, and no black map spaces unaccounted for. Not really sure what to do other than go through the rigmarole of getting back to the Tower again.
