enjoying the game, but interface with the lab is eluding me, i click on the hings but all it says is invalid sum. i have puzzle 2 & 3 unlocked (puzzle 1 is still got me stumped) do i need to have all 3 unlocked before i can do anything with lab?
that makes me feel a bit better, i was bashing my head against that puzzle for a few days
i should have seen how the lab worked, i just didn't think those areas interacted.
i have yet to beat 83, that one is a tough one. other than that your lab and puzzles added a nice layer onto the game
keep up the good work :D
