So one of my favourite games was Jumpming Jack on the Spectrum.
Found a clone for Pico-8.
With fellow UKVACer Hurray Banana, made some adjustments to the code to :
(1) Implement a scoring system
(2) Hiscore Save
(3) Game difficulty (Holes get bigger by levels)
Hope this GIF gives you an idea of the gameplay:

Still to do : Get rid of glitches from the original. The collisions between monster and lemming are NOT sprite based and seem to be causing problems in later levels.
