I mentioned this on a YT comments section and it didn't seem to be common knowledge, so thought i'd share the (full) article here, but Probe tried various different approaches to the games look, before settling on the version we finally saw. Thought i would share...
The cartridge game i found lacked enough levels to justify the price..i bought it on day 1. The Mega CD version however i loved. Glad the info is new to folks. ACE was the only magazine i saw detailing it.
