Alright, so there's a big chance I will never find this game, and what I do remember is very vague. Growing up, I remember playing this like a pixelated isometric adventure game on my brother's Motorola Razr V3. Possibly the character's hair looked cyan, and the sprites were a lot like classic Legend of Zelda. I was so young, I remember being unable to read any of the text, but I remember being able to slash enemies with a sword (possibly goblins), and you would be playing in a forest, and there are little dungeons you can enter. I remember also a lot of areas were inaccessible because of stupid rocks in your way.
I also remember the game coming preinstalled on Motorola!
If the date helps, I think I was playing these games around 2010, maybe?
Thank you to anybody who takes the time to read my post :) Sorry if my descriptions aren't helpful!
Also sidenotes! The sprites kind of look like old Pokémon games, but much more crude!
