I agree with the sentiment that there was a bit too much obscuring going on. I have since changed the cyclops to 8 power and only obscure 8 tiles away. The 12 powered stone watcher has since replaced the cyclops role and is limited to higher level dungeons. We have also updated the obscure effect to be multi-colored so it's easier to identify where and which obscure enemy is nearby!
Not everyone is a hard core minesweeper logician and items are trying to cater to those people. We have gradually toned down items and made them more expensive. If you think the game is too boring and easy we have since added some challenge modes. Can you beat the game with the ascetic on DungeonSweeper+++?
