Jonas Fischbach of Retroid fame released another Game Boy Color homebrew pearl named Into the Blue. You have a vertical play field with panels raising from the bottom. The panels can be rearranged and will disappear if three (or more) matching panels are lined up in a horizontal or vertical row. The game is over if a panel touches the upper border of the play field.
This game is inspired by a Sega Genesis title named Megapanel, which is is widely forgotten today – probably because it was only released in Japan.
