Hey, how did you know that my favorite level also was my last completed level? Elementary psychology, I guess
Anyway, yesterday I completed a few more. Level 17 & 19 were surprisingly easy (pleasant surprise). 20 was also quickly solved, but mostly through a little trial and error.
Level 18, The Trap, was interesting. I solved it without using the portals at all. I used the "switch position block" both to reach the switch button and to escape the inner area. As this required some "arcadey" dexterity & timing, I suspected this solution was not the intended one and decided to check with the C64 walkthrough video on Youtube. To my surprise it was solved in an even more arcadey way - via the aforementioned running jumps! He uses them to move against the conveyor-belt/1-way track. Now, this is not possible in the Vic version, because running jumps work differently in the C64 version (but still inconsistently between left and right). Then I returned to the level and completed it with the portals, in what I think is the intended way.
I will most likely return to your game and play more levels later on, but for now, I have a 2-year backlog of Vic games to check and play
