Played the new build (20004962). Ran your ?debug autopilot through all 12 levels twice (perfect aim and with aim noise): both reached the win card without a game over, 0 page errors, and every new capsule showed up (including SKIP on level 9). Real key presses: the level-clear now goes straight into the next level, so the keyboard gap at the old shop is gone. Enter still does nothing on the YOU DID IT card (Space works), if you want it to match the title and game-over screens.
One new one, from the +10 per cube change: cubes still fall and get caught for the ~2.6 s after the last boss dies, but the best score is saved at the moment of the kill. So the win card says NEW BEST! with SCORE 3505 and BEST 3315 next to each other, and 3315 is what gets saved. I got exactly that gap (+190, 19 cubes) in all 3 of my winning runs. Checking 'if (score > save.hi) save.hi = score' again in showWin() (or wherever a cube adds to the score) would fix it.
