At last, I'm getting responses again. I do browse the forums often, and noted the lack of traffic combined with that other quest getting released around the same time (Was it Freedom's Quest? I think it was.), I figured it would be awhile before I'd get some feedback.
The quest is in a wierd state of limbo-beta. On one hand, all the main content is there. The odd colored doors are unlocked using the same colored magic keys, every empty weapon slot gets filled, etc. On the other hand, every build since the ones I mentioned have had changes that broke the quest. As of the latest Mac build, the doors still don't work, now jumping is broken, and some bosses don't fire projectiles correctly (luckily, that one is an easy fix I can do). Also, the enemy editor improvements have happened since then, meaning some enemies would have their weaknesses changed. I've made posts to attempt to fix the other bugs.
At current moment, my to-do list for non fixes:
Add any missing animations to the player avatars.
Add a well-hidden developer room.
Add minor bonus dungeons that have no purpose other than bragging rights (mainly a boss rush dungeon).
Maybe add NPC player avatars, to let the player know they are not alone (story-wise).
Figure out a better tutorial for newcomers (a tutorial dungeon may be nice, but I can't use normal strings due to scripts drawing the character; strings would render the player invisible).
Gameplay experience wise, has anyone:
Seen all the endings? (Spoiler: all 8 of them.)
Tried out the new game plus modes? (Passwords rewarded with endings.)
Beaten the well hidden dungeon that is a major mind screw? (Location of entrance shown on this thread and hinted in-game.)
Also a gameplay hint: the magic keys are collected in a specific order, always in the 'Level 8' of a dungeon set, and the order is the same as the difficulty curve. (1st->2nd->etc)
And another: The floors don't match up with the dungeon set order.
4F -> Invalid, please refer to Level 7-9 for details.
3F -> 6th
2F -> 5th
1F -> 1st (1st Quest)
B1 -> 2nd (2ndQuest)
B2 -> 3rd
B3 -> 4th
B4 -> 7th (4th Quest)
One final detail, since my last post, I no longer have access to ZC on a windows, so I can only update based on when Mac builds come out and can't test to see if the following windows build will work.
