Pro Retro art style
The simple pixel art is full of charm for those that enjoy the bloated 8 bit style, and it takes a lot of it's inspiration from games such as the original Doom and Minecraft. The blocky textures, chunky pixels, and 2D enemies are a definite nod to old school gaming. It's a visual feast for retro lovers.
Pro It gives you a fresh experience every run
The dungeons, items, and enemies are procedurally generated. This ensures the levels are truly random each and every time, with items, bosses, traps, and secret rooms scattered about in new places every run. You'll never play the same map twice.
Pro Barebones gameplay but still quite fun for a few hours
One More Dungeon is a fairly basic first person dungeon crawler. Roaming around dungeons, picking up power ups, killing enemies, avoiding traps, and using a variety of different weapons. There's no looking up or down, so combat is pretty straightforward. Run up and hit a monster, or line up your ranged attack. Bosses have a few simple mechanics but nothing fancy. Dungeons are randomly generated so you'll never play the same one twice.
Pro Interesting ranged weapon play
Staves act as the ranged weapon to shoot projectiles at your foes, as well have some magical attributes like freezing, poisoning, and burning.
Staff use is limited as ammo comes in the form of various crystals (fire, ice, and acid) which can be found scattered around the maps. Some staves, such as the Ice Beam Staff, only consume ice crystals. However others, like the Mirror Staff which causes your shots to bounce off walls, requires 1 crystal of each type to use.
Some enemies are also weak to certain damage types like fire or acid, so you'll have to plan and manage your crystals appropriately if you want to do max damage with staves.
Between the sheer variety of staffs and micromanaging your crystals to use each staff to it's full potential, everything comes together into a ranged weapon system that's both interesting and functional.
Pro You can customize the gameplay with Mutators for an added challenge
Every time you kill an enemy, you earn points which can be used to purchase Mutators. These Mutators are game options that change your experience a bit, and are a great way to try something new or add an extra layer of difficulty. Some examples of Mutators include starting the game with 1 hit point, reduced view distance, extra power ups, and extra enemies. There are quite a few to choose from, and you can activate 2 at a time which means you can mix and match them to find your perfect challenge.
Con Melee weapons feel imbalanced to play with
The melee weapons seem to hit a little off center and to the right of where you're actually aiming. You can adjust for this with a little practice, but it just doesn't feel good to control. Also, the range on most melee weapons is so low that they're almost effectively useless since you have to be practically right on top of enemies. During the early game, you'll be too weak to be up close and personal with enemies, so the sheer difficulty discourages any kind of melee play.
Con Repetitive gameplay
The randomly generated maps are very similar to one another. In most cases, they require a bunch of backtracking due to bad layouts, meaning a lot of play time is spent walking instead of fighting. Enemies either blindly charge at you or sit at the same predetermined distance to shoot at you, without any kind of noticeable strategy behind their actions. Overall, the similar maps and predictable enemies just don't change things up enough from level to level to retain your interest for long.
