Update 1.20 is getting close. I've been actively reworking the trouble spots in the level design. I've been listening carefully to all the feedback and weighing my original intentions against the experiences of actual players to see if the intended result was achieved.
Highlights:
Some trouble spots were brought to light in a few locations including the bug hive and the scrolling lava pit puzzle in the area adjacent to the final area. Those have been reworked to eliminate the confusion.
Other level design changes include removing some of the one way passages that drop you back a few screens and just make you have to work your way back. It created an unexpected maze like feel to certain areas and unintended confusion.
Some needlessly difficult spots have been toned down a bit including eliminating the long fall drop shafts in the final area. The final area has been looked over to improve playability.
Some platforms have been reworked where slopes at key jump locations were making jumping difficult. Other changes to improve navigating in tight spots have been made.
An alternate route to the Science Ship boss has been added. The original route remains and is now more of a shortcut. The new route is more intuitive. The Science Ship is going to be fully mapped now as well.
New hidden features have been added. Additional shortcuts and alternate routes have been added. I was impressed by some of the exploits I saw in some of the YouTube videos I watched so I accommodated them in a few spots. It's possible to break the sequence of item acquisition. I'm interested to see who can figure out how to do it first

Snarfblam is working on making the starting health always 99 rather than 30. Also all heal stations will replenish missiles as well.

Lots of other improvements that will be listed in the change log!
