is desktop dungeons worth getting?
A huge YES.
But... you need to understand what you're getting.
First, it's incredibly well designed and extremely well balanced. Every 'dungeon' is generally 1 level and 1 level only (some have hidden optional sub rooms). You pick your adventurer per level (race, class, loadout, etc) and if you die, that's okay, try again. The goal is pretty much to beat every dungeon with every combination, because all those races and classes and skills create very unique experiences. It's fun to unlock new classes and then try to learn them.
Now, once your in a dungeon it's almost like a complex (but fun!) math problem. Exploration (non-combat) heals you, and you'll discover lewt and enemies on the board. You'll know everything you need to know - -how much damage a hit will do, what level an enemy is... and you need to figure out a way to kill enough of them to get powerful enough to kill the boss. This can be easy or difficult, depending...
In theory, since every dungeon is only one level (one screen), an absolute math wizard that could think ten turns ahead could beat every dungeon in 5 minutes or whatever. In practice, you're going to be internally debating what to kill and how to kill it, in what order, to maximize your experience gains (you can get to level 10 in each dungeon, but may be able to clear it earlier).
Part of the game is 'figuring it out'... for example, you get bonuses for killing creatures higher level than you, but to do so you often need to engage in 'neat tricks' in which you figure out class/race specific ways to heal mid-battle. You may also find altars to various gods you then need to master (they might reward or punish you based on your actions in the dungeon). there are also bonuses/challenges for clearing dungeons in various ways.
There's no way I can do justice to this game with a description. You need to like puzzles, you need to be decent at basic math (although it'll show you the basics in the interface, figuring out whether you can pull off those 'neat tricks' may involve thinking a few turns ahead.
Anyway, as you defeat more and more dungeons, you build up your town, unlocking new races and classes and abilities and better equipment to take on your adventures. Dying on a level is no big deal, since it's more about solving each dungeon with tons of different characters... there's no 'you' character. It's like a roguelike that was boiled down to it's very essence and then rebuilt as a dungeon sim + town building + math problem.
Highly recommended if you're not completely turned off by above description. I'd buy it again if I had to.
The game was a gem when it was still a simplistic little 'proof of concept' project, but the nice full version now is so finely tuned it's insane.
Is to day the last day of the sale? They usually do the repeat day toward the/at the end
They repeat in the middle too.
