I bought a bundle because this was in it, so i was hoping this would be worthwhile. Dwarf Tower isn't a bad game, but it's one of those indie games where developers don't want to bother with proper single player and you just have to hope there are other people interested in multiplayer. This game doesn't seem to be dead, so there's that.

However, i wouldn't recommend it. Aside from lacking a non-redundant singleplayer component, the core gameplay is flawed. There's very little strategy involved, you mostly just have to hope to get the right cards (like the tabletop game Saboteur). You can spend many turns waiting for an attack card or a solution to an enemy attack (fire/flood). There's no way to influence this aside from the alchemist lab, which is rare and explodes randomly for some reason.

Aside from that, deckbuilding is done through some cryptic system that requires you to know the game quite well. I love deckbuilding but you have to give people some indication of what they're doing. This could have been a fun game where you start as an apprentice, fight enemies and earn new cards over time. Instead, it's a half-finished game dominated by luck.
