AlchiDS is a Nintendo DS puzzle homebrew. The object is to combine ingredients to advance to the next level.
From the developer:
"Oye Oye!
J'vous present my new homebrew made speed: AlchiDS!
I started it last night, after reviewing an old flash game that I had not played for a long time: Naturalchemist.
So it's a simple concept game, addictive (* Arg *) and effective. Your objective is the discovery of the rarest ingredients in combination with others.
To do this, align 3 or more similar ingredients to create an ingredient next level. There are a total 15 different ingredients.
