I tried to find some good games in Linux, since there is not much game development in Linux. Recently, I played Cave Story. The drawing is looking old, but the storyline is good, just like an expected Japanese game. And there are 3 different endings.
The game is not easy to play. So, I finally, try to game hack it using GameConqueror. Then, these are the memory address:
81c8614 HP 81cce84 Polar Star / Spur Lv 81cce98 Missle Lv 81ccea4 Missle bullet 81cceac Fireball Lv 81ccec0 Bubbler Lv 81ccecc Bubbler bullet 81cced4 Blade / Nemesis lv
Unfortunately, GameConqueror cannot save and open the address list.
Still need to follow a game guide so that you will not miss any secret from the game.

I downloaded it, looks really good! Thanks for the link, I’d never heard of it.
Welcome izzy. The storyline is good, it is better to follow the game guide. This is the guide I used.
