Ok for 172 to start you will need 2 keys, 5 oxygens and 2 bags of cement before going through the yellow teleport. Then after collecting the 4 keys shoot through the walls to get access to the remaining keys near the red teleport. You will then need to work out how to get the bag of cement and access to the 2 keys in the bottom left corner. I hope this is helpful without giving away too much. Final hint, you can get the single green note with one key once the red teleport is removed

Finally completed after 9 days. This is one of the best puzzle games I have ever played. If you think 148 or 172 are hard, you should try the last level 185 pwou.

I'm completely stumped on level 107 (AQDS). Can anyone offer a hint? However I do it, I'm either a key short, or one lot of oxygen short.

Can I get a hint for lvl 128?
I've been busting my ass over it for a couple of days now :P
How should I collect the three keys on the top? Are the oxygen and cement on the right side relevenat at all?

Hints for 129: you only need to teleport once (using the blue teleport). You need the most southwest oxygen. You don't need any money.

Fun. The only issue I've noticed is it seems to get stuck between levels quite often. I have to hit F1 to pull up the help screen just to move on to the next level. And yes, the password system is obsolete and annoying.
