Thanks rjshae!

ABOUT THIS GAME

Delve into the shifting dungeons on your hunt for the Yithidian orb, but getting it might just be the easy part. Delver is a single player first-person action roguelike dungeon crawler, just like you wished they used to make.

Slay monsters, blast wands, hoard potions, and loot everything.

• A silky smooth mix of 90s FPS combat with classic RPG mechanics.
• In these dungeons once you're dead you stay dead. Permadeath means that when you die, you begin each run into the dungeon anew.
• Tough as nails gameplay will test your skills, no grinding will save you here.
• A procedural dungeon that will keep you on your toes, no two runs will ever be the same.
• Delicious chunky pixels!

Easy to pick up gameplay, but difficult to master. The dungeon has been waiting for you.

Destructoid's Jim Sterling plays the alpha version of Delver, and gives his opinion of the game in this new video.

Jim Sterling, ever the rogueish type, jumps into yet another roguelike first-person adventure, taking Delver out of Early Access and into your lives. Watch as he gets killed, endlessly, by traps. All the time. Bloody hell.

Armchair Arcade has a new video preview for the roguelike minecraft game Delver.

Delver is an Indie game that was recommended to me by a friend and this is the first time I take a look at it. It is basically one of these old text based Rogue like games that has turned into a nice 3D game featuring nice pixellated graphics reminiscent of those found in Minecraft. It is a tough game and I only seem to be able to last a couple of minutes. It works quite intuitively and I am liking this a lot even in its current Alpha state.

Delver is a new first person RPG roguelike dungeon crawl with pixels. The game is available on Steam Early Access. 

 “Delver is in an unfinished beta state at the moment and has it’s share of bugs and rough edges that need filed down, but it’s very playable even in this unfinished state. Help us guide the direction of the game with your early access help and feedback.”
