Hello an thanks for the feedback :)
1. Yes, I agree. The game really needs some better ambient. The sound asset needs improvement in general.
2. That’s how the controls are in grid-based dungeon crawlers. Just like in Grimrock and Eye of the Beholder and many others. It allows to have free mouse cursor instead of mouselook. It also makes collision detection and pathfinding more easier.
3. It doesn’t matter if you push the box to the corner. In the same room there is a rock which you can use to keep the pressure plate down. And you can smash the box, there is a magical staff inside.
4. Hod did you hit the skeleton? Did you click it with the hand cursor? You need to equip your weapon first by pressing R key or clicking the weapon icon in the bottom panel. The hand cursor will change to the sword cursor (or the crosshair cursor if you have a ranged weapon). After this you can attack.
You run against the skeleton by moving into it, right? The skeleton did resist because your strength level is no high enough for pushing enemies. The higher your strength, the more likely your pushing will success. You can check your strength level on the right side of the top panel. You can also try to keep pushing your enemy constantly. It will success eventually. It just takes more effort.
And you could not move? Did you check something was blocking your way? There is another skeleton besides the one you encountered in the dungeon. Maybe that was blocking your way.
