First of all, very few people knew about this game, and even at the time, it was rare to see a cartridge of this game on the market. I accidentally played this game at my classmate's house when I was in primary school. Unfortunately, I didn't remember its name at that time, just remembered its unique gameplay. It wasn't until more than 20 years later that I found it in an FC game forum where I got help by describing the gameplay I remembered.
