O-Chan no Oekaki Logic

O-Chan no Oekaki Logic (おーちゃんのお絵かきロジック) is a Japan-exclusive puzzle game based on the popular nonogram game. The game is considered to be a spin-off of Sunsoft's Hebereke series. Its first release was on the PlayStation on September 8, 1995, and would later be ported onto other platforms ever since. The game has received 2 sequels. It is the only game in the Hebereke series to feature Utsuzin as the main villain, rather than Unyohn. A European version, named Oh-Chan's Logic, was planned, but was cancelled.

Plot
O-Chan and Hebe are walking on a grass field. All of a sudden, Utsuzin suddenly captured Hebe in a UFO. O-Chan tries to run after him, but she's too late. Then she ventures to rescue Hebe from Utsuzin's lair.

The ending shows O-Chan waking from her bed, indicating (but not explaining) that it was a dream.

Gameplay


The game presents the player with a puzzle grid. The player should chisel the grid; if done correctly, the player will win the game.

The game also has a multiplayer mode in which the player must chisel the grid in order to beat the other player.

The game even has an edit mode in which the player can create their own puzzles.

The Sega Saturn version included a story mode in which the player must verse opponents that come out of their way. The player can also complete to get better times on that mode, as they are timed.

The game has a tutorial mode, which teaches the player how to play the game.
