Sonic Eraser is a simple Columns-esque puzzle game released under Sega Game Toshokan. It also features Sonic.
It's probably most notable for being the only Genesis Sonic title (not counting Sonic Classics) to remain absent from official compilations, though it very nearly got into Sonic Gems Collection. It does have a fan translation, at least.

The unused shrinking sprite from Sonic 1 makes a return here, still unused!

Sega Game Toshokan leftovers
The Game Toshokan ROM is attached to the game due to how titles worked for the program. However, here it appears to be a unique, modified version. The entire game is loaded into RAM, leaving the only used portions to be some key functions for file decompression and other basic routines.
