Soleil, with releases across Europe, France, Germany, Japan (beta), and Spain, indicates a potential pan-regional release for the Sega Genesis. The nature of the game itself—genre, mechanics, and developer—requires further research.  The multiple regional releases suggest a level of success or interest in the title across different markets.  The Japanese beta release, in particular, suggests potential variations or adjustments made for different market preferences and gameplay.  Locating reviews or development details from the period would yield more specifics.  Without further information, assuming a common gameplay style across the region is an assumption requiring further research and verification.
