didnt realise you could get to 'a short break' from the shaft, thats a bit of a nuicence as you're not suppose to go that way into that room. I did try to get in to 'a short break' from there and couldn't. Testing, testing, testing!!! Going to the bottom right exit takes you further into the level, but if you thought 'untypical cave' was hard, the room after is a complete nightmare (the one screen i hated testing).
The instant deaths are a bit cheeky, but they were all intentional (as with 'see!'), just to add some more flavour. I was trying to keep everything as Manic Miner-y/Jet Set Willy-ish as possible.
It's a pity you gave up cause there are lots of other screens in the level that will, not only have you pulling your hair out, but you'll probably end up ripping your eyes out just to have an excuse not to play it! The last 4 screens are a particular delight!
Thanks for trying out my level, but alas, no toffee crisp for you!
