"Croc" tech demo from 1996. Possibly used in presentations, when Argonaut was still looking for a publisher. Played on a real hardware, not by emulator.
The controls are very stiff and the jumping is unprecise. Collision problems with several boxes/containers as well. Also - you can't finish the level without collecting all 3 Gobbos. The tech demo ends after 4 levels, with a very glitchy boss fight (early Flibby the Ladybug).
