Gosh it's hard. Getting a feeling to make a guide on countering each enemy type, but I don't think anybody would care. Great game and a fun game, good job.
One way to improve the manual switching would be a way to change weapons left and right, for example using z and x or some other pair of keys to switch weapons left and right. That way it would be easier to switch between weapons, rather than searching frantically for the right number key.
For those of you complaining about auto switch, TURN IT OFF. Button in top left corner of armory. Something that complex is bound not to be perfect. The fact that it's even there is a work of progamming genius. Use 1-6 to manually switch weapons. Might help if you don't like the auto.
Do you know how LOOONGGG I have been looking for a game even similar to this? Commanding armies like a true field strategist, not the whole "one man RTS", but true legion vs. legion battle. Even in the time-management games, I have looked for this, but here I find it. Thank you.
So, a villager waltzes into my dungeon, breaks ALL my traps, entrances my monsters into avoiding him and missing all of their attacks, steals my gold, and walks out the same way he walks in. I am not a happy man.
