A small roguelike game that was released earlier this year is Quest of Dungeons. I've been playing with this and it's quite nice. While it has been released it's also still in development, with added content and minor tweaks being released now and again.
The plot is simple, journey into a dungeon to kill the Big Foozle and recover the MacGuffin. You get to choose four character classes, a Warrior, a Wizard, an Assassion (archer) and a Shaman which combines melee with magic. So far I've only tried the Warrior, so I can't comment on the other classes.
Each floor has about 4 different monsters with the option for stronger versions appearing if a Quest requires you to kill one. Boss Encounters can also pop up anytime and anywhere. There are 4 difficulty levels and the game has "Hell" (the hardest one) as the default one.
I've played around 3 hours and already I've had those LOL moments that only roguelikes can deliver. Two examples:
# I start a game, only one door from the starting room, next room is empty, one other door. Open that, Boss Encounter. I'm slaughtered in 4 blows.
# In my longest-running game so far I reach level 5. I quickly find 2 quests to kill 2 named monsters. I proceed a little further and find one of the named monsters, it hits me pretty bad and I need an escape route. In the room is a portal which will send me to another portal on the level. I jump through, only to emerge RIGHT NEXT to the other named monster, which promptly finishes me off.
The biggest gripe I have with the game right now are the thieves. You encounter them on Level 4, they make a "steal" attack, which has a failure chance. But if it succeds, the thief either clears out a whole inventory slot, or steals around 3% of your total gold. Clearing out a whole inventory slot wouldn't be so bad if it wasn't for the fact that HEALING POTIONS STACK, and it only took a handful of thief monsters for me to have "lost" all my health potions. What's worse, killing the thieves doesn't bring the stuff back.
The developer is aware of this and will address this in the next update, which promises to be rather big.
The game's only $5 on Steam, one can do a lot worse than pick up this game.
