I guess there is another one: Cosmic Spacehead for Game Gear and Mega Drive. I just played it last weekend on the Game Gear (not an emulator) and find it lovely. It is amazing how they managed to implement it for the game gear considering the extremely limited hardware.
The game is a verb based graphical adventure with jump&run passages between locations (you don’t have to repeat the J&R mini-game when changing location again).
Btw. If you like retro 8-bit sega consoles, then checkout http://www.smspower.org/ Some people develope new games for the game gear.
- No dead ends. (No dead ends regarding the puzzles, but you can die in a J&R passage. But you can save the game and on an emulator you can save at any time you want.)
- No unfair or non-sense puzzles.
- Level: medium - easy.
