Thanks for playing, and for your comments! Sorry you had a hard time with the first door though; I did wonder if I'd made that obvious enough, and the answer is probably 'no'. Also, if you don't open the door first, it's quite a long walk back up to the switch, which is a little frustrating. I'll try and tutorialise that a little better in the next build!
And yes, you did complete the game! I'm thinking that maybe a 'To be continued' before it returns to the title screen would be a bit less confusing.
Cheers!
