From the Hippopotamus website; "This is the first (and so far the last) `demo'-production from HpD. It was released at the Analogy party Dec -92 as a participation in the intro compo (placed 3rd (in this compo intro meant one screen of action)). It was coded for A500, but it can be run on other setups too (try booting PAL first). Requires kick 1.2 or better and OCS chipset or better."
