Crypts of Avaritia is a combination of randomly generated dungeons together with a first person view with gameplay similar to Heretic/Hexen combined with Dungeon Hack, Ultima Underworld, Dungeon Master, Might & Magic, Daggerfall, Arena and other games in the same genre. The gameplay will not force the player into melee combat as many other RPGs do, instead choice will be given to approach any problem the way the player seem fit, just like in Deus Ex. As such there are many non-combat skills for the player to upgrade. There are strong survival-mechanisms coupled to the gameplay, such as the player need to sleep, eat and drink water. You can also break bones, bleed and get poisoned.
I prototyped a wall climbing feature (with place holder graphics) after a nice suggestion on RPG codex and tried to capture a video of it. Up next is to make the wall climbing affect the stamina depletion, perhaps with such harsh punishment that the player will have to consider wether it is worth it or not to climb the wall. If a enemy is on top of the ledge the player do not want to arrive fatigued and weakened. If the player wants to climb alot of walls, they would have to invest a lot of points in increasing their stamina. Another possible system would to allow player to invest in climbing, and higher level means the player is able to cover more distance or hang on to the wall for a longer time before the he looses his grip, I will tinker with it and see what is most suitable.
Anyways, hope this is view-able (climbing starts at 50 seconds or so)
