Okay. I have to go to bed. Made it to the very top again (top of mountain visible on screen, second time in a row). Didn't finish because when the boss is aiming the laser, the coloured pads are grey and I got clipped by a red dot which I thought I was above, but barely not.
The boss is great. I still think the difficulty of everything is a bit much, and can't help but continue wondering aloud if the game doesn't need a New Game plus mode to capture much of what you guys are doing with the biomes currently (which, if they are meant to be harder than the Indiecade/XOXO/PAX build, means you are calibrating for masters of your game).
