Ookey... let's see...
-You played as a boy; you could write his name, and change some basic genetics.
-It had a RPG vibe, pixelated art (not bad, but not rly great too) I remember maps were like in Zelda's games in GBA.
-Combat System was like in Zelda too, I believe (can't rly remember, but I know they werent turn based like in pkmn).
-It had a characteristic that really got me when I played the game (I must've had like 10): you could choose your character's type of magic, things like electricity, light, darkness (lol), fire, poison?, and a LOT more, but I can't remember so much, it's been like more than 6 years now.
-Now, I can't remember really well, but you had a friend (can't remember if female or boy) that waited for you beside the town's entrance. S/he gave you a sword, or told you to buy one. S/he didn't accompany you.
-In one part of the game, I think outside the town they were being attacked by monster (This was what triggered your adventure), i remember either they were skeletons or ghosts.
-First cave or dungeon I entered was really dark, you couldnt rly see much, but it was full of monster that I think had circular bodies and glowed in the dark. But i'm not sure about this; could be mistaken.
-The game site, I remember, was black, or the game itself had a dark scheme of colors. This was... before 2012? (Game was probably way more older, tho. Maaaybe 2005-2009?) The game was for PC, online, you know, like a flash game. Free. Amateur, too.
-Style of art of the game kinda makes me remember Children of Morta, but it's not that one for what I can see simply because i'ts kinda new.
I didn't finish the game, because I think I got stuck at some part and gave up, but idk, it would be cool to play it again. I tried to search it, but I couldnt find it. helps?
