So I decided to check a few of these out based on their borders, but the only one that really impressed me was something called "Rock'n! Monster!". It's Super Game Boy enhancements are almost akin to that of DK94 with how much gets colorized.
It's basically a Puyo clone but with colors INSIDE colors that come out when the primary color vanishes. It's a lot more fun than it sounds, if a bit on the easy side.
