the correct answer solution is already impossible because the puzzle states with white to move.  the above sequence to reach the position is with white having just moved, thus it would be black to move.  the position is impossible to reach with white to move

As another comment points out, no it isn't:

1. Nf3 Nf6 2. Ne5 Ng4 3. Ng6 Ne5 4. Nxh8 Ng6 5. Nxg6 Nc6 6. Nf4 Nb8 7. Nh3 Nc6 8. Nc3 Na5 9. Nd5 Nc6 10. Nb6 Nb4 11. Nxa8 Nc6 12. Nb6 Nb4 13. Ng1 Nd5 14. Nc4 Nc3 15. Na3 Nb1 16. Nxb1

however, it has to be white who made the last move, because with those pieces missing, black cannot have made the last move, as none of his other pieces can move until a pawn moves, and no pawn has moved

Google Play Store won't let me buy because it's apparently for an older Android version, amy chance of an update ?

if you're concerned about security -- scan it with your antivirus, and disconnect your computer from the internet while playing.  none of the information *should* leave your computer.  Alternately, you can just put in a phony social security number, and edit it before you actually mail anything in.

Any chance keys/doors could have a tiny number in one corner, or different numbers of stripes or something?  I'm not colorblind but I'm still having trouble with orange vs. red because I keep my monitor dim to avoid migraines.

Edit:  I just got to 1-8 and I wish you'd mentioned hovering keys/doors earlier, that solves my problem.  Still might be trouble if I couldn't see *any* key/door colors as I"d have to hover each one, but this is workable for me

it's intentional.  Even if you remap the "close an application" binding on linux, alt-f4 still closes this specific game.

keep going and you will get the jump upgrade
