The platform-jumping thing is much too difficult. It took me about half of Area 2 to get the logic behind the controls, but even then I kept falling to my ignoble death. The programming of it was pretty nice - it seemed like a lot of thought was put into the platform auto-run and drop-onto-platform-after-fall. I died too many times to appreciate them though.
Things I liked about this sequel: the non-scrolling screens. It made the action more manageable, and also more tense and packed. The new character types livened things up a bit too.
I like the look/concept. It would be nice if the game mechanics were better explained, and if the bomb timers could be set by clicking anywhere on the time scale (rather than having to click and drag). The level select menu is quite clever, but difficult to use.
