Simple times these were. Both games were logical puzzles, which ment finite levels. Solving the levels in themselves were the reward. As I said, simpler times, no expectations.
Both games were popular, but I liked Atomix way better.
Why?
Because that gave more leaway, more space to mistakes. With levels advancing the solutions became more complex of corse, aka. the game became harder.
Shokoban had more whatwe could call "game elements". To get to the stages you had to step in an elevator, press the number of the level, and do what you could.
Here I always missed the game did not keep track of what levels you already done, and when all got finished a nice "congratulation!" would have been nice...
And the game was like monocrome: babyblue and babypink.

Atomix on the other hand was way more dynamic. And the time-limit was disabled, so we could play it w/o frustration.

This screenshot is from the remake, but couldn't find some higher level shots all the sudden.
Of course neither of these games surrendered to your smile.
