Vandar {l Wrote}:- I've tried to alt tab to another application, but OD kept popping back in front.
I usually play in windowed mode and I don't have problem with switching application. I will have a look when using fullscreen.
Vandar {l Wrote}:- I had problems to spawn a first imp, because I had forgotten that it was in the "spells" menu. That might be a trap for players who don't know or don't remember DK very well anymore.
Yes, It might not be straight forward to use spells to summon imps (we call them kobolds). It will probably be better when we will have some tutorial maps. I will have a look at the help menu and open an issue about it if it is not clear enough.
Vandar {l Wrote}:- I couldn't find out how to save and load games.
Because there is no possibility to save/load a game yet

It will come later. ATM, the game is at a stage where we can begin to think about it (now that nearly all game mechanisms are functional).
Vandar {l Wrote}:There was a minor lighting glitch when I poitioned the cursor on a certain field of the treasury - a whole line of wall tiles darked down a notch in that case. Maybe a siode effect of the fog of war code? No problem though.
I've never seen that. If you can reproduce it, could you please save the replay and post it ?
Vandar {l Wrote}:Music changed when some of my monster got angry. I guess that was intended, and want to tell that the feature works

That happens when there is a fight

And you can press space to go to the place. I will add a chat message to warn about the fight, too, tonight.
Vandar {l Wrote}:The gold is used up quickly. Not a problem for my testing, but I was surprised how fast the gold that I had mined was spent again.
Everything is configurable (creature fees, room/traps prices, payday frequency, ...). For now, they are pretty high because it is easier to test but we will definitely need to decrease. On the other hand, need for gold will be the easiest way to achieve the game average length we are aiming for (between 30 to 60 minutes in multiplayer). The most gold is needed, the most aggressive players are advantaged. In any case, gold has to be very usefull to give a real bonus to players taking the risk to try to get many in early game (and thus, putting their dungeon at risk).
Vandar {l Wrote}:Is mana used for something yet?
Yes, for spells. ATM, we only have 2 spells available: summon kobold and call to war (makes all your idle creatures go to where you cast the spell). I was also thinking of implementing a bolt spell but I need a mesh and I've not found any suitable yet (but I've not looked much either).
Vandar {l Wrote}:My firewall blocked OD, though, could that be a problem here?
It will make that you cannot play multiplayer (the feature is functionnal).
