Wow dude, this is really amazing for your first game if it is.
My first game was absolute poop. And still most are quite bad.
I liked the connection between the title and the game play: "taking the wrong turn can kill me. "This makes the game stand out among other games.
I also liked how there come new obstacles as you progress through the dungeon.
The alien, slime then the ant and the GOLEM! Although the game is about progressing through the dungeon, I actually found it more enjoyable to kill monsters.
Would have wished killing them made me stronger. Maybe you could add a leveling system to your character, where each kill provides stats to upgrade your hiker? e.g. speed, strength.
especially if you follow the suggestions to remove the turn waittime.
Also wanted to buy something with the coins. Perhaps you could make it so that you can buy armor/ weaponry with the coins?
From the description I get that you wanted to complete a full game.
Well nicely done, with the well polished art and music it truly seems like a fully finished product.
