There are several questions about Grimrock future. I'm not a specialist, as you see later in post

1. Would be added in addons/sequel some invisible and/or barely visible objects (and monsters, that you can expect only by sounds of course

2. Would be there any possibility to monster's interaction with the environment, objects on the floor? Can you make them to take in hands/use/throw in you object, lying in front of them? To create some sort of poltergeist?

3. Could be added something imitating sky for open areas (before entering dungeon)? And what about caves, would they look great, or we will see only hand-made catacombs? Insectoid tunnels would be very interesting, IMO

Could be made a sort of not-gridded ground, for upper floors of big caverns /rooms (involving two or three floors in them)?
4. What about exploding and poisoning vials (as throwing weapon) for advanced alchemists? Traps, made by rogues and placed on the ground? And not-my-own-traps securing some areas?
5. Some new abilities for prisoners like block (using a shield in hand) or riposte with light weapon (daggers or rapiers)?
6. Dual-wielded weapon (not as in EoB) - a weapon pair, using both hands as one inventory object and acting at once. Balanced of course

There could be more and more questions, but I think that first few of these are unrealistic already
