It wasn't until I was looking into Super Game Boy borders that I discovered this game even existed. After having played the Super Famicom version, I wasn't expecting to see this game again but here I am.
This game is pretty similar to its Super Famicom counterpart. It has a mode where you try to clear the board of similar shapes for a high score and a mode where you try to clear specific challenges to advance. The challenge mode has 100 stages and a password system so you can come back to them anytime. Originally I was trying to tackle every stage individually when I became fed up and started entering random passwords. It got me all the way through the game except I never did find level 99's password. Oh well.
